Answer:

49% probability that Mitchell will be a goalie today

Step-by-step explanation:

If Coach White coaches, the probability of being goalie is 0.55.

Coach White has a 70% probability of coaching.

If Coach Jackson coaches, the probability of being goalie is 0.35.

Coach Jackson has a 100-70 = 30% probability of coaching.

What is the probability that Mitchell will be a goalie today?

This is 55% of 70% plus 35% of 30%

Then

P = 0.55*0.7 + 0.35*0.3 = 0.49

49% probability that Mitchell will be a goalie today
