The accompanying table shows the percentages of residents in a large community when classified according to gender and presence of a particular allergy.

Suppose that the selection of a person is considered a trial and the presence of the allergy is considered a success. For each case, identify the numerical value of p and find the required probability.
(a) Four persons are selected at random. What is the probability that none has the allergy?
(b) Four males are selected at random. What is the probability that none has the allergy?
(c) Two males and two females are selected at random. What is the probability that none has the allergy?
