A doctor has 3 doses of flu protection vaccine left. He has 6 women and 7 men who want the medication. If the names of 3 of these people are selected at random, determine the probability that 3 men's names are selected. The problem is to be done without replacement. Use combinations to determine the probability.
There are total 13 patients, 3 can be selected in 13C3 ways
If 3 men are selected, this can be done in 7C3 ways
Required probability = 7C3/13C3
= 35/286
= 0.1224
