    (a) The probability that a person selected at random from the general population is senior citizen who will get the flu this season is 0.14 x 0.18 = 0.0252

    (b) The probability that a person selected at random from the general population is a person under age 65 who will get the flu this year is (1 - 0.14) x 0.23 = 0.86 x 0.23 = 0.1978

    (c) (a) 0.85 x 0.18 = 0.153

    (b) (1 - 0.85) x 0.23 = 0.15 x 0.23 = 0.0345

    (d) (a) 0.52 x 0.18 = 0.0936

    (b) (1 - 0.52) x 0.23 = 0.48 x 0.23 = 0.1104
