If A and B throw two dice 100 times each simultaneously, then the probability that both of them will get even number as the total score at the same time in all the throws is
Options
- A1 6 100
- B1 4 100
- C1 2 100
- D3 4 100
Correct answer
B. 1 4 100
Step-by-step solution
Consider a be the number of die A and   b be the number of die B . It is given that a + b is even. Therefore,   a and b are both even or both odd. Thus, the probability of both even or both odd is, P = 1 2 Thus, for 100 th  time, the required probability is 1 4 100 .
