Interest centers around the nature of an oven purchased at a particular department store. It can be
either a gas or an electric oven. Consider the decisions
made by six distinct customers.
(a) Suppose that the probability is 0.40 that at most
two of these individuals purchase an electric oven.
What is the probability that at least three purchase
the electric oven?
(b) Suppose it is known that the probability that all
six purchase the electric oven is 0.007 while 0.104 is
the probability that all six purchase the gas oven.
What is the probability that at least one of each
type is purchased?
