To answer this question, we need to find the winning probability in either case.

Probability = no. of outcomes / total no. of possible outcomes

<u>When Hope pulled her defender :</u>

Total no. of games = 9

No. of games won = 3

Winning probability = 3/9 =1/3

<u>When Hope left her defender :</u>

Total no. of games = 10

No. of games won = 6

Winning probability = 6/10 = 3/5

We know that , 1/3 < 3/5.

So, Hope should not pull her defender, as the winning probability is better when Hope left her defender.

Answer : A. Hope should not pull her defender.

<h2>Answer:</h2>

Option: A is the correct answer.

Hope should not pull her defender.

<h2>Step-by-step explanation:</h2>

<u>When Hope has pulled her defender:</u>

The team has lost 4 times, tied 2 times, and won 3 times.

Hence, the total number of times she meets her goal is:

6 times

(Since the goal is to either tie or win the game )

Hence, the probability that she meets her goal is:

6/9=2/3=0.66

<u> When she has left her defender in the game:</u>

The team has lost 1 time, tied 3 times, and won 6 times.

Hence, the total number of times she meets her goal is:

9

Hence, the probability that she meets her goal is:

9/10=0.9

As the probability of meeting her goal is more when she left her defender in the game is more.

Hence, Hope should not pull her defender.
