Final answer:
The probability that exactly two of the five selected entrees for the banquet menu contain bacon is 10.
Step-by-step explanation:
To calculate the probability that exactly two of the five selected entrees for the banquet menu contain bacon, we need to use the combination formula. There are 5 entrees and we want exactly 2 of them to contain bacon, so the number of ways to choose 2 from 5 is C(5, 2) = 10. The total number of possible outcomes is C(5, 5) = 1. Therefore, the probability is 10/1 = 10.
