If Coach White coaches, the probability of being goalie is 0.55.
weeeeeb [17]

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

An auto transport truck holds 12 cars. A car dealer plans to bring in 1,006 new cars in June and July. If an auto transport truc
marin [14]
To find the number of full trucks we can do 1006 / 12. This gives us 83.8333. That is, 83 full trucks and a bit left over.
The bit left over is the answer to the second part, the last truck. 0.8333 is the same as 10/12, so the last truck will have 10 cars in it. If we didn’t know that fraction, we could find the answer by saying 12x83 = 996. 1006 - 996 = 10.

So the final answer is: 83 full trucks and 10 cars in the last truck.
