Number from 1 to

Prime numbers between 1 – 50:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47

Multiples of five:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50

Number of prime number from 1 to 50 = 15

Number of multiples of 5 from 1 to 50 = 10

Total number of paper slips = 50

Probability of getting a prime number

⇒

Probability of getting a multiple of 5

⇒

From the calculated probabilities, we can observe that the probability of getting a paper slip which has prime number is 0.30 and the probability of getting a paper slip which has a multiple of 5 is 0.20.

Hence, choosing a prime number would be better because the probability of getting a prime number paper slip is higher than probability of getting a multiple of 5.
