The probability that a visitor at the mall buys a pack of candy is 60%. 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 choices
A) 0.284 B) 0.326 C) 0.432 D) 0.548 E) 0.652
One case is: candy - candy - no candy   The probability is 6/10*6/10*4/10 = 144/1000   There are 3 such cases, so we should multiply this probability by 3.   P(exactly 2 buy candy) = 144/1000 * 3 = 432/1000=
