INTERPRET
Question 1.
If you place 14 marbles in a bag with 7 red, 4 orange, and 3 black, what is the probability of blindly pulling a red marble from the bag?
Answer:
Probability of blindly pulling a red marble from the bag = 0.5.

Explanation:
Total number of marbles in a bag = 14.
Number of red marbles = 7.
Number of orange marbles = 4.
Number of black marbles = 3.
Probability of blindly pulling a red marble from the bag = Number of red marbles ÷ Total number of marbles in a bag
= 7 ÷ 14
= 1 ÷ 2
= 0.5.

Question 2.
If there are 20 males and 15 females in your class, and the teacher wants to appoint one person to be in charge of attendance, what is the probability that this person will be a female?
Answer:
Probability that this person will be a female = 0.42.

Explanation:
Number of males in the class = 20.
Number of females in the class = 15.
Total number of students in the class = Number of males in the class + Number of females in the class
= 20 + 15
= 35.
Probability that this person will be a female = Number of females in the class ÷ Total number of students in the class
= 15 ÷ 35
= 3 ÷ 7
= 0.42.

Question 3.
A survey was taken at school and all 525 students were asked if they belonged to a club. 212 people responded that they did belong to a club. What is the probability that if you randomly chose a person walking down the hall, that this person would belong to a club?
Answer:
Probability that randomly chosen a person walking down the hall, that this person would belong to a club = 2.47.

Explanation:
Total number of students were asked if they belonged to a club in the school = 525.
Number of students responded that they did belong to a club = 212.
Probability that randomly chosen a person walking down the hall, that this person would belong to a club = Number of students responded that they did belong to a club ÷ Total number of students were asked if they belonged to a club in the school
= 525 ÷ 212
= 2.47.

Question 4.
Someone mistakenly put three boxes of hardboiled eggs in with the regular farm eggs that totaled 156 boxes. What is the probability that someone buying a box of eggs will get a box of hardboiled eggs?
Answer:
Probability that someone buying a box of eggs will get a box of hardboiled eggs = 52.

Explanation:
Total number of boxes of eggs = 156.
Number of boxes of hardboiled eggs mixed mistakenly with boxes of regular farm eggs = 3.
Probability that someone buying a box of eggs will get a box of hardboiled eggs = Number of boxes of hardboiled eggs mixed mistakenly with boxes of regular farm eggs  ÷ Total number of boxes of eggs
= 3 ÷ 156
= 52.

Question 1.
Ramon surveyed a group of 50 people at the town meeting about the expansion of the town zoo and the construction of a bike path. He found that of the 50 people he surveyed, 32 people supported expanding the zoo and 30 people supported constructing a bike path. Twelve people supported both projects. Fill in the Venn Diagram to represent the results of the survey.

How many people supported the town zoo only? ____________
How many supported the bike path only? _____________
Answer:
Number of people supported the town zoo only = 20.
Number of people supported the bike only = 18.

Explanation:
Total number of people he surveyed = 50.
Number of people supported expanding the zoo = 32.
Number of people supported constructing a bike path = 30.
Number of people supported both projects = 12.
Total number of people surveyed = Number of people supported expanding the zoo + Number of people supported constructing a bike path
= 32 + 30
= 62.
Number of people supported the town zoo only = Number of people supported expanding the zoo – Number of people supported expanding the zoo
= 32 – 12
= 20.
Number of people supported the bike only = Number of people supported constructing a bike path – Number of people supported both projects
= 30 – 12
= 18.

Question 2.
The manager of the local clothing store wants to know which jeans to stock for the upcoming back-to-school sale. He reviews the numbers from last year’s sale and finds that the store sold 120 pairs of jeans. 80 were boot- cut, and 60 were stone-washed. Assuming the store only stocked those two styles of jeans, how many of the jeans sold were both stone-washed and boot-cut?

How many of the jeans were just stone-washed and not boot-cut? _____________
How many were just boot-cut and not stone-washed? _____________
Complete the Venn Diagram to show the data.
Answer:
Number of people of the jeans were just stone-washed and not boot-cut = 60.
Number of people were just boot-cut and not stone-washed = 40.

Explanation:
Number of pairs of jeans the store sold = 120.
Number of pairs of jeans were boot- cut = 80.
Number of pairs of jeans were stone-washed = 60.
Total number of pairs of jeans were boot- cut and stone-washed = Number of pairs of jeans were boot- cut + Number of pairs of jeans were stone-washed
= 80 + 60
= 140.
Total number of pairs of jeans were both boot- cut and stone-washed = Total number of pairs of jeans were boot- cut and stone-washed – Number of pairs of jeans the store sold
= 140 – 120
= 20.
Number of people of the jeans were just stone-washed and not boot-cut = Number of pairs of jeans were boot- cut – Total number of pairs of jeans were both boot- cut and stone-washed
= 80 – 20
= 60.
Number of people were just boot-cut and not stone-washed = Number of pairs of jeans were stone-washed  – Total number of pairs of jeans were both boot- cut and stone-washed
= 60 – 20
= 40.

Question 1.
Phil first rolls a 6-sided number cube then flips a coin. Draw a tree diagram that shows all the possible outcomes. How many different outcomes are there? How many outcomes exist where Phil rolls an even number and he flips a coin “heads”?
Answer:
Total different outcomes = 12.

The coin is fair, the probabilities of getting a head and a tail are equal = 12 .
The probability of getting an even number on a die is 36 = 12 (because among 6 results there are 3 even numbers)

Explanation:
Phil first rolls a 6-sided number cube then flips a coin.
Number of outcomes of a cube Phil first rolls = 6.
Number of outcomes of a coin Phil second rolls = 2.
Total different outcomes = Number of outcomes of a cube Phil first rolls × Number of outcomes of a coin Phil second rolls
= 6 × 2
= 12.
The coin is fair, the probabilities of getting a head and a tail are equal = 12 .
The probability of getting an even number on a die is 36 = 12 (because among 6 results there are 3 even numbers)

.Question 2.
Felicia is laying out her wardrobe for an upcoming vacation. She will be gone 4 days. She lays out 4 shirts (blue, black, red, yellow), 3 pairs of pants (black, tan, white), and 3 pairs of shoes (black, brown, red). Draw a tree diagram to show all of the different combinations of outfits that Felicia could wear on the trip. How many combinations are there? ______________
If Felicia brings only two pairs of shoes but adds another shirt, how many possible combinations will she have? ________________
Answer:
Total outcomes of combinations she have = 40.

Explanation:
Number of days she will be gone = 4 .
Number of shirts she lays out = 4 (blue, black, red, yellow)
Number of pairs of pants = 3 (black, tan, white)
Number of pairs of shoes = 3 (black, brown, red).
Outcomes of wearing shirts = 4 × 4 = 16.
Outcomes of wearing pants = 4 × 3 = 12.
Outcomes of wearing shoes = 4 × 3 = 12.
Total outcomes of combinations she have = Outcomes of wearing shirts + Outcomes of wearing pants + Outcomes of wearing shoes
= 16 + 12 + 12
= 28 + 12
= 40.
If Felicia brings only two pairs of shoes but adds another shirt, how many possible combinations will she have?
Number of shoes she has = 2.
Number of shirts she has = 5.
Outcomes of wearing shirts = 4 × 5 = 20.
Outcomes of wearing pants = 4 × 3 = 12.
Outcomes of wearing shoes = 4 × 2 = 8.
Total outcomes of combinations she have = Outcomes of wearing shirts + Outcomes of wearing pants + Outcomes of wearing shoes
= 20 + 12 + 8
