Question

At the school carnival, Jade has a games booth with a spinner. The banner at her booth reads "30% chance of winning!" What is the chance that a player may not win?
70%

50%

40%

15%

Answer 1

Its 70%. 

Because if you have 30% out of 100%, then all you have to do is subtract 30 form 100 and you'll get 70%.
Hope that helps! :)
