Solution
The number of handshakes that can be made out of 6 people can be calculated using the formula for combinations, which is n(n-1)/2, where n is the number of people.
Step 1: Substitute the number of people (n = 6) into the formula.
Step 2: Calculate 6(6-1)/2 = 6*5/2 = 30/2 = 15
So, 15 handshakes can be made out of 6 people. The answer is d.15.
