# What will be the Probability that This Slip Bears a Prime Number? If

Natural numbers 4 to 15 are written on different slips (one number on one slip), kept in a box and mixed well. Renu picks up one slip from the box without looking into it. What is the probability that this slip bears a prime number?

- 1/3
- 5/12
- 2/5
- 3/11

**Answer: (1) 1/3**

**Explanation:-
**The number of slips = 15 – 3 = 12

The prime number between 4 to 15 = 5, 7, 11, 13

Then, the number of slips bears a prime numbers = 4

Then, the probability of the slips bears a prime number = 4/12

= 1/3

Hence, the answer is (1) 1/3.
