Question

Emma will roll 2 number cubes labelled 1 through 6. She will record the sum of the two numbers after each roll. She will roll the 2 cubes 540 times. How many times should Emma expect the sum of 5?

Answer 1

She will roll 5 180 times

Explanation:

There is two cubes rolled 540 times therefore,

540 x 2 = 1080 This is how many times a number was rolled

There is an equal probability of rolling any of the 6 numbers therefore

1080 ÷ 6 = 180 This means that she will roll any number on the dice 180 times.

Hope this Helps!!!
