Romashka [77]

Answer:

0.0975 or 9.75%

Step-by-step explanation:

Assuming that no engines fail simultaneously, the probability that exactly one engine fails is the probability that the first engine fails (15%) multiplied by the probability that the second engine does not fail (100% - 35%):

$P = 0.15*(1-0.35)\\P=0.0975$

The probability of exactly one engine failure is 0.0975 or 9.75%
