Explanation / Answer

a) Answer: (43/154)*(43/154) = 0.0779642 = 0.0780

since the probability that first selected subjects are both group A and type Rh+ is 43/154

Again, the probability that second selected subjects are both group A and type Rh+ is 43/154 since selection

procedure is with replacement

Required probability = (43/154)*(43/154) = 0.0779642 = 0.0780
