Question

From 10 identical cards, numbered 1, 2, 3, ……, 10, one card is drawn at random. Find the probability that the number on the card drawn is a multiple of

 2 or 3

Sum

Solution

Total outcomes = 10
i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Favourable outcomes = 7

i.e. 2,3,4,6,8,9,10

P(E) = `7/10`
