Question

Cards marked with numbers 1, 2, 3 ……… 20 are well shuffled and a card is drawn at random. What is the probability that the number on the card is:

divisible by 3

Solution

Total possible outcomes=20

Favorable outcomes for a number divisible by 3=3,6,9,12,15,18

Number of favorable outcomes=6

P(divisible by 3)= 6/20=3/10
