Question 1.
Are any of the events impossible?.
Answer:
Rolling an 8 is impossible because the number cube has numbers from 1 to 6.

Question 2.
The probability of event A is \(\frac{1}{3}\). The probability of event B is \(\frac{1}{4}\). What can you conclude about the two events?
Answer:
The probability od event A is lower than \(\frac{1}{2}\), so this event is unlikely to happen.
Because od the same reason, event B is also unlikely to happen.
But, \(\frac{1}{3}\) is greater than \(\frac{1}{4}\), se event A is more likely to happen than event B.

Question 7.
A jar contains 8 marbles marked with the numbers 1 through 8. You pick a marble at random. What is the probability of not picking the marble marked with the number 5? __________
Answer:
Sum of probability from some event and his complement is equal 1.
P(Event) + P(Complement) = 1
Event in this problem is picking the marble with number five.
Complement is not to pick marble with number five.
P(Picking marble with number five) + P(Complement) = 1
We have 8 marbles.Probability to pick marble with number 5 is \(\frac{1}{8}\).
\(\frac{1}{8}\) + P(Complement) = 1
Write one as \(\frac{8}{8}\).
Subtract \(\frac{1}{8}\) from both sides in equality.
\(\frac{1}{8}\) + P(Complement) – \(\frac{1}{8}\) = \(\frac{8}{8}\) – \(\frac{1}{8}\)
P(Not to pick marble with number five) = \(\frac{7}{8}\)

Question 8.
You roll a standard number cube. Use the probability of rolling an even number to find the probability of rolling an odd number. __________
Answer:
The sum of the probabiLities of an event and its complement equals 1.
First, find the probability of rolling an even number
Sample space for a standard number cube is {1, 2. 3, 4, 5, 6} and number of ways to roll an even number is 3.
Texas Go Math Grade 7 Lesson 5.1 Answer Key 5
The probability of rolling an even number is \(\frac{1}{2}\).
The probability of not rolling an even number is the same as the probability of rolling an odd number.
Hence,
P(even number) + P(odd number) = 1 Substitute \(\frac{1}{2}\) for P(even number)
\(\frac{1}{2}\) + P(odd number) = 1 Subtract \(\frac{1}{2}\) from both sides
P(odd number) = 1 – \(\frac{1}{2}\)
P(odd number) = \(\frac{1}{2}\)
The probability of rolling an odd number is \(\frac{1}{2}\).

The probability of selecting black pen is \(\frac{3}{4}\).

Texas Go Math Grade 7 Lesson 5.1 Answer Key 28
The probability of selecting red pen is \(\frac{1}{4}\).

The sum of the probabilities of an event and its complement equals 1.
P(event) + P(complement) = 1
P(black pen) + P(not black pen) = 1 Substitute \(\frac{3}{4}\) for P(black pen).
\(\frac{3}{4}\) + P(not black pen) = 1 Subtract \(\frac{3}{4}\) from both sides.
P(not black pen) = 1 – \(\frac{3}{4}\)
P(not black pen) = \(\frac{1}{4}\)
The probability of not selecting black pen is \(\frac{1}{4}\).

P(red pen) + P(not red pen) = 1 Substitute \(\frac{1}{4}\) for P(red pen).
\(\frac{1}{4}\) + P(not red pen) = 1 Subtract \(\frac{1}{4}\) from both sides.
P(not red pen) = 1 – \(\frac{1}{4}\)
P(not red pen) = \(\frac{3}{4}\)
The probability of not selecting red pen is \(\frac{3}{4}\).

P(not black) + P(not red) \(\stackrel{?}{=}\) 1 Substitute \(\frac{1}{4}\) for P(not black) and \(\frac{3}{4}\) for P(not \(\frac{1}{4}+\frac{3}{4} \stackrel{?}{=} 1\)
1 \(\stackrel{?}{=}\) 1
True

Question 22.
Communicate Mathematical Ideas A spinner has 7 identical sections. Two sections are blue, 1 is red, and 4 of the sections are green. Suppose the probability of an event happening is \(\frac{2}{7}\). What does each number in the ratio represent? What outcome matches this probability?
Answer:
The numerator in a fraction represents the number of times event occurs, and the denominator represents total number of equaLity likely possible outcomes.

The number 2 shows that the spinner has 2 section with the same color, in this case, blue color, and the number 7 represents the number of sections spinner has.

The outcome that corresponds to this probability is that the spinner lands on a blue section.
