Question 611034
Walton Pharmaceuticals experiments with a new allergy medication using a sample of 17 allergy sufferers. Six sufferers are randomly selected from the group for the first trial. What is the probability that the 5 youngest are chosen?
----
# of groups of 6 that have the 5 youngest: 5C5*12C1 = 5*12 = 60
# of random groups of 6: 17C6 = 12376
