Question

A number is selected from 1 to 25. The probability that it is prime number
2/3
1/6
1/3
5/6​

Answer 1

Answer:

Given: A number is selected from 1 to 25

Total number of possible outcome = 25

Let E = Event of getting a prime number

Prime number from 1 to 25 are = 2, 3,5,7, 11,13,17, 19, 23

No. of outcomes favorable to E = 9

Probability,P(E) = Number of favourable outcomes / total number of outcomes

P (E) = 9/25

Hence, the Probability of getting a prime number from 1 to 25,P(E) is 9/25.
