The probability that a visitor at the mall buys a pack of candy is 40%. If three visitors come to the mall today, what is the probability that exactly two will buy a pack of candy?	Choose the correct choice from the following:
A) .288	B) .147	C) .189	D) .063	E) .027
One case is: candy - candy - no candy   The probability is 4/10*4/10*6/10 = 96/1000   There are 3 such cases, so we should multiply this probability by 3.   P(exactly 2 buy candy) = 96/1000 * 3 = 288/1000=
