Question

a dice is rolled . if the outcome is an odd number , what is the probability that is a prime number​

Answer 1

Odd no. outcomes = 1, 3, 5

Prime numbers in these odd numbers are 3 and 5.

Therefore,

P = No. odd prime outcomes ÷ Total outcomes

=> 2 ÷ 3 = 2/3

Answer : 2/3

Answer 2

Step-by-step explanation:________

Probability = Number of favourable outcome/ Number of all possible

outcomes

_______________________________

A dice is rolled

Then possible outcomes ( odd numbers) = 1, 3, 5

Number of possible outcomes = 3.

favourable outcome ( prime numbers) = 3, 5

Number of favourable outcome = 2

So probability of getting prime numbers = 2/3
