Answer:
P(three $25 prizes are chosen)=[tex]\frac{12}{53}[/tex]
Step-by-step explanation:
A radio station runs a promotion at an auto show with a money box with 12 $25 tickets, 11 $5 tickets, and 10 $1 tickets.
20 dummy tickets
total tickets = 12+11+10+20=53
3 $25 prizes are chosen
there are 12 , $25 tickets
probability = number of occurrences / total occurrences
P(three $25 prizes are chosen)=[tex]\frac{12}{53}[/tex]
