Question

Find the probability:

A number from 10 to 22 is drawn at random. P(an odd number) Express the probability as a decimal. Round to the nearest hundredth

Answer 1

{10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22} = 13 numbers to choose from

{11, 13, 15, 17, 19, 21} = 6 odd numbers out of those 13

P(odd number) = 6/13 = 0.46
