Question

At a recent graduation at a naval flight school, 18 Marines, 10 members of the Navy, and 3 members of the Coast Guard got their wings. Choose three pilots at random to feature on a training brochure. Find the probability that there will be 1 of eac.

Answer 1

The probability of selecting 1 pilot from each branch out of the total number of pilots is 0.016 (approximately).

Step-by-step explanation:

To find the probability that there will be 1 pilot from each branch (Marines, Navy, and Coast Guard), we need to calculate the probability of selecting 1 pilot from each branch out of the total number of pilots.

There are a total of 18 Marines, 10 Navy members, and 3 Coast Guard members.

The total number of pilots is 18 + 10 + 3 = 31.

The probability of selecting 1 pilot from each branch is (18/31) * (10/30) * (3/29) = 0.016 (approximately).
