Answer:
Sue played 30 games
Step-by-step explanation:
Probability is typically given as a fraction or percentage where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. Since Sue's won 12 games and estimated the probability to be 0.4 or 4/10, you can set up a proportion, or equivalent ratios, to solve for the number of games she played:
Cross multiply: 4x = 120
Divide by 4: 4x/4 = 120/4
Solve for 'x': x = 30 games
