Question

A number is chosen at random from 1 to 10. Find the probabbility of selecting a 9 or greater.

Answer 1

2/10 or 20%

Nine or greater is 2 numbers out of a total of ten. 2/10 turned into a percent is 20% because 2*10=20 and 10*10=100

Answer 2

Because you have ten numbers you could select, 10 is your denominator. Selecting a 9 or greater leaves you with two possible options therefore 2 is your numerator.

This means that you have a 20% chance of selecting a nine or greater.

ANSWER: 2/10 or 20% chance
