What is the probability of choosing a particular grand prize? (grand prize) What is the probability of not choosing that particular grand ? (not grand prize)

well it be 2 out 5 for the probabitity of choosing the grand prize

OpenStudy (sachintha):

If the car and trip are both grand prizes you are correct. If not there is a 20% chance of getting a grand prize.

OpenStudy (anonymous):

will it be 3 out of 5 of not getting the grand prize

OpenStudy (sachintha):

In my opinion there would be only one grand prize. So the probability of getting a grand prize is 1/5 and a normal price is 4/5.
