1. A number is selected at random from 40 to 50 inclusive. What is the probability that the number is prime number?
- A. 3/11
- B. 3/11
- C. 3/11
- D. 3/11
Answer: Option E
Explanation:
Total number of numbers = 59 - 40 + 1 = 20
Prime numbers : 41, 43, 47, 53, 59 = 5 in total
So, the probability = 5/20 = 1/4
