Question

A twelve-sided die with sides labeled 1

 through 12

 will be rolled once. Each number is equally likely to be rolled.

What is the probability of rolling a number greater than 10

?

Answer 1

Hi Kamya!

A 12 sided die has the numbers 1 - 12. The numbers greater than 10 are 11 and 12. Since there are two numbers greater than 10 of the 12 total, we'll divide 2 by the total individual numbers on the die (12).

2 (numbers greater than 10) / 12 (total numbers) = 1/6

So there is a 1/6 or 0.1666 chance of rolling a number greater than 10!
