Answer:

Probability of losing = 0.514

Probability of getting money back = 0.108

Probability of winning = 0.378

Step-by-step explanation:

The number of tickets that lost = 57

The number of tickets where she got her money back = 12

The number of tickets that won = 42

The total number of tickets = 57 + 12 + 42 = 111

∴ The probability of her losing = $\frac{57}{111}=0.514$

The probability of getting her money back = $\frac{12}{111}= 0.108$

The probability of winning = $\frac{42}{111}=0.378$
