Question

A stack of cards is numbered 1 to 21. Kelly pulls one card from the stack. What is the best approximation for the probability that the card is an even number?
5%
21%
48%
52%

Answer 1

The correct answer is 48%

There are 10 even numbers from 1 to 21.

That makes the probability of an even number 10 out 21.

10 / 21 x 100 = 48%
