Hope is the coach of the Wilson High School girls' soccer team. There are 3 minutes left in the game they are currently playing,
NISA [10]

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.
