<PRE><B>Question 841689</B>
A statistics textbook chapter contains 66 exercises, 12 of which are essay questions. A student is assigned 16 problems. What is the probability that at least one is essay?
--------
Binomial Problem with n = 16 and p(essay) = 12/66 = 2/11
--------------------
P(at least one) = 1 - P(none are essay)
----
= 1 - (9/11)^16
= 1 - 0.0403
= 0.9597
