Question

2) Identical twins come from the same egg and hence are of the same sex. Fraternal twins have a 50-50 chance of being the same sex. Among twins the probability of a fraternal set is p and an identical set is q=l-p. If the next sets of twins are of the same sex, what is the probability they are identical?(10p)

Sa Given that Probability of frate smalfis PA : P Probability of identical lis PO = 2 - 1-P P (same sex ) identical ) - P(51) : ) P (same sex Ifraternal) P (SF)= 504. -0.5. P(1/5) - PLS n)*P(1) PLS) PLS) P(SA) P(2) +P (S/F) PCF) = 1xq + / -P = 1X (1-P) +P/2 1-2+P/2 2-2p te - - 2 - 2 1.0.58. 1x(1-P) P(1/5) 1.0.50 I-P 1-0.5p.
