Given :  Five distinct numbers are randomly given to persons 1 to 5. Persons 1 and 2 compare their numbers and the winner is the one having the smaller number. The winner compares with person 3 and so on.

To Find  : What is the probability that person 1 wins 2 times

Solution:

probability that person 1 wins 2 times  out of 4 comparisons

= (1/2)²

= 1/4

probability that person 1 wins 2 times the complete round

Each person has probability to win = 1/5

winning 2 time probability =  (1/5)² = 1/25
