Working Out Probability Help Please?
A supermarket gives away a scratch card with each transaction. There are 15 types of scratch card, each equally likely to be given. Only one type entitles the recipient to a money-off voucher. If a customer has five transactions with the supermarket, choose the option that is closest to the probability that he receives at least one voucher.
