Question

Numbers from 1 to 20 are written on 20 separate slips. The slips are put into a box and mixed thoroughly. One slip is drawn from the box randomly. What is the probability of drawing a prime number?

Answer 1

Dear Student,
Total possible outcomes = 20.
Favourable outcomes = Prime numbers between 1 to 20.
Favourable Outcomes = 2,3,5,7,11,13,17,19
Favourable Number of Outcomes = 8
Probability = Favourable Outcomes/Total Outcones = 8/20 =2/5
