Question

At the school carnival, Jade has a game booth with a spinner. The banner at her booth reads "70% chance of winning!" What is the chance that a player may not win?
15%?
30%?
35%?
50%?

Answer 1

The answer is 30% because if there is a 70% chance then minus 70% from 100% you get 30%

Answer 2

30% because 100-70=30 just add a percent sign after the number.
