Question

fair die is rolled. Then , the probability of not rolling a number less than 5 is *​

Answer 1

Answer:

In rolling a die, the sample space, S={1,2,3,4,5,6}

Therefore, n(S)=6

Let D be the event of getting number less than 5.

D={1,2,3,4}

Therefore, n(D)=4

P(D)=

n(S)

n(D)

=

6

4

=
