a. two qualified people

b. one qualified and one unqualified person (think about different ways this could happen).

c. At least ONE qualified person. Hint: Use the complement law.

for a)i got the answer 4/15. 8/15*7/14

for b) i got the same answer

for c) the prob of picking both unqualified is 7/15*6/14= 1/5 so using complement would mean that i would take 1-1/5 to get 4/5???

**PsyDAG**, Thursday, January 24, 2008 at 10:53amThe first two answers are right.

For C, to get "At least ONE qualified person," you want the probability for one qualified person*plus*the probability for two qualified persons.

I hope this helps. Thanks for asking.
