Ответ:
88.98% probability that a randomly selected car had automatic transmission or air conditioning or both
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
37 had automatic transmission only
44 had air conditioning only
61 had automatic transmission
This already counts those with both automatic transmission and air conditioning. So 61-37 = 24 had both.
So![D = 37 + 44 + 24 = 105](/tpl/images/0617/5016/a191c.png)
Total outcomes:
118 cars sold, so
