Question

A dice is rolled once ,the probability of getting a prime number

Answer 1

Answer:

So from here we can say that if we throw a die then among these six faces one face must occur. Now the favourable outcome is to get an odd prime number, so between 1 to 6 the odd primes are 3 and 5, i.e, only two. So we can say that the probability of getting an odd prime number is 13

Answer 2

Prime numbers on the faces of a dice are 2, 3 and 5

∴ P(rolling a prime no) = 3/6 = 1/2
