Answer is 3/8.
probability to come head on face is 3/4. but the question is what is the probability that other side is head?
since there are 2 coins, in which 1 had both side head and 2nd have one head n one tell. so the probability for other side to come head is 3/4 * 1/2 = 3/8
if i am wrong, please correct me!!!! |
