A biology professor has two graduate assistants helping her with her research. The probability that the older of the two assistants will be absent on Any given day is 0.08, the probability that the younger of the two will be absent on Any given day is 0.05, And the probability that they will both be absent on Any given day is 0.02. Find the probabilities that
(a) Either or both of the graduate assistants will be absent on Any given day;
(b) At least one of the two graduate assistants will not be absent on Any given day;
(c) Only one of the two graduate assistants will be absent on Any given day.
