Suppose that in a given town, 60% of the population is under age 40 (event A). It is found that the proportion of residents under age 40 who support mandatory inoculation is 0.72. The proportion of residents over age 40 who support mandatory inoculation is 0.52. Let event B = support mandatory inoculation. Are the events A, B independent? O Yes, they are because P(B N A) is not equal to P(B)× P(A) O Yes, they are because the occurrence of A does not affect the occurrence of B. No, they are not because P(A) equals P(A|B) O No, they are not because P(B|A) is not equal to P(B|A')
