Question

If a die is rolled once, then the probability of getting an odd prime no. is
(a) 0 (b) 1 (c) 1/3 (d) 1/2

Answer 1

When a dice is rolled once, the possible events are { 1 , 2 , 3 ,4 ,5,6 }

Events in which we get a odd prime are 2 { 3 , 5 }
Total number of events = 6 .

We know that,
Probability = Favourable outcomes / Total outcomes.

Probability of getting a number which is a odd prime = 2/6 = 1/3

Hope helped !

Answer 2

Hey!

______________________

Possible events = 6
Number of odd numbers that can come= 2 (3,5)

Probability = Favourable outcomes/Total outcomes

P.E= 2/6
P.E= 1/3

Thus, Correct Option- (c) 1/3
