A test is conducted by randomly selecting 14 customers for that airline and observing whether they had lost their baggage. Provide answers to at least 6 decimal places for the following:

(a) The probability that exactly 2 customers lost baggage is .

(b) The probability that at least 12 customers lost baggage is

**Reiny**, Wednesday, December 8, 2010 at 8:14amprob of losing = 8/100 = 2/25

prob of not losing it = 23/25

prob(2 out of 14losing it) = C(14,2) (2/25)^2 (23/25)^12 = appr .214

b) prob (at least 12)

= Prob(12) + prob(13) + prob(14)

= C(14,12) (2/25)^12 (23/25)^2 + .....
