Question

18 card are numbered from 11 to 29 if 1 card is chosen at random what is the probability that it contains digit 2​

Answer 1

61%

Explanation:

First we need to fine how many of the cards contain "2", which if we count them out(12, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29), we know the answer is 11.

That means there 11 out of 18 cards meet our criterion, and therefore the chances of drawing a card with a 2 on it are 11/18.

11/18 = 0.61 = 61%
