Suppose that 25.9% of car engines will fail if they have not had routine maintenance in the past five years. If routine maintenance is given to 18 cars, what is the probability that exactly 7 will not have engine failure? Round your answer to six decimal places.
Added by Alejandro C.
Step 1
We know that the probability of a car engine failing without routine maintenance is 25.9%, which means the probability of a car engine not failing (success) is: \[ p = 1 - 0.259 = 0.741 \] We are looking at 18 cars, so \( n = 18 \). We want to find the Show more…

Suppose that 23.9% of car engines will fail if they have not had routine maintenance in the past five years. If routine maintenance is given to 21 cars, what is the probability that exactly 10 will not have engine failure? Round your answer to six decimal places.

A firm maintains 22 cars for business purposes. From past experience, it is known that approximately 10% will require major engine service during a one-year period. What is the probability that at most 1 car will require major engine repair next year? 0.0480 0.2407 0.6608 0.9520 0.3392
