Question

A dice is rolled 100 times, then the minimum number of times'1' is occurred on the top face is

Answer 1

n(S)=100

Let A be the event in which we get 1

:.n(A)=100

:. P(A)=n(A)÷n(S)

=100÷100

=1

:.P(A)=1

Answer 2

Probability of getting 1 on the top face =  

Number of Favorable Outcomes / Total Number of Possible Outcomes

Probability of getting 1 on the top face =  100/100

                                                                = 1

The number 1 on the dice can appear on the top face all the times wen the dice is rolled.Thus Number of Favorable Outcomes is taken as 100.
