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 = [tex]\frac{57}{111}=0.514[/tex]
The probability of getting her money back = [tex]\frac{12}{111}= 0.108[/tex]
The probability of winning = [tex]\frac{42}{111}=0.378[/tex]
