(i) 57.2% 143 (ii) 0.572 (iii) 0.428 (iv) 250 (c) A couple has 3 children. Find the probability of having exactly two girls? (ii) (iv) E [1] [1] E (d) Human blood is grouped by its Rh factor. From the following table choose 1 at random. 0 A B AB Rh+ 37% 34% 10% 4% Rh- 6% 6% 2% 1% person Find the probability that the person has Rh negative (Rh-) given that the p has type B. P(Rh negative | Bgroup) = [2] 1121 (e) A package contains 12 resistors, 3 of which are defective.
