On one side of a coin there is the number 0 and on the other side the number 1. What is the probability that the sum of three coin tosses will be 0 if a 1 is the value of the first coin flip?
Choose the correct choice from the following:
A) 0/8.  B) 1/2.  C) 1/5.  D) 3/8.  E) 1/3.
Assume the coin is unbiased.   Possible sums from 3 tosses = 0,1,2,3   O and 3 are possible in only 1 case each. (0,0,0 or 1,1,1)   1 is possible in 3C1 = 3 cases. (1,0,0; 0,1,0 or 0,0,1) or   similarly, 2 is possible in 3C2=3 cases (1,0,1; 1,1,0; 0,1,1)   So answer will be 0/8. Option A.   Its impossible to get a total value of 0 if a 1 has been showed
