Problem #7: The probability that a randomly selected box of a certain type of cereal has a particular prize is 0.18. Suppose that you purchase box after box until you have obtained 3 of these prizes. (a) What is the probability that you purchase exactly 8 boxes? (b) What is the probability that you purchase at least 11 boxes?

a) A box contains 8 chips numbered 1 to $8 .$ Two are chosen at random and their numbers are added together. What is the probability that their sum is $7 ?$ b) A box contains 20 chips numbered 1 to $20 .$ Two are chosen at random. What is the probability that the numbers on the two chips differ by $3 ?$ c) A box contains 20 chips numbered 1 to $20 .$ Two are chosen at random. What is the probability that the numbers on the two chips differ by more than $3 ?$
