Male =blood type A is 20. type b is 8, type AB is l6, type O is 11
Female =blood type A is l5, type B is 6, type AB is l0, type O is l4
(a) What is the probability that the person selected is a FEMALE?:: 0.45
----------------------------
(b) What is the probability that the person selected has blood type O?::0.25
----------------------------
(c) Given that the person selected is a MALE, what is the probability that their blood type is AB? 0.16/0.55
------------------------------
(d) Given that the person's blood type is A, what is the probability that the person is a FEMALE? 0.15/0.35
------------------------------
(e) What is the probability that the person selected has blood type B or is a male? 0.14 + 0.55 - -0.08 = 0.61
