When a die is thrown, then probability of getting a six = 16
then, probability of not getting a six = 1 − 16 = 56
If the man gets a six in the first throw, then
probability of getting a six = 16
If he does not get a six in first throw, but gets a six in second throw, then
probability of getting a six in the second throw = 56×16 = 536
If he does not get a six in the first two throws, but gets in the third throw, then
probability of getting a six in the third throw = 56×56×16 = 25216
probability that he does not get a six in any of the three throws = 56×56×56 = 125216
In the first throw he gets a six, then he will receive Re 1.
If he gets a six in the second throw, then he will receive Re (1 - 1) = 0
If he gets a six in the third throw, then he will receive Rs(-1 - 1 + 1) = Rs (-1),
that means he will lose Re 1 in this case.
Expected value = 16×1 + (56×16) × 0 + (56×56×16)×(−1) = 11216
So, he will loose Rs 11216.
