During a raffle drawing, half of the ticket holders will receive a prize. The winners are equally likely to win one of three prizes: a book, a gift certificate to a restaurant, or a movie ticket. If there are 300 ticket holders, predict the number of people who will win a movie ticket.
So first of all.
"half of the ticket holders will receive a prize."
This means that half of the 300 ticket holders will recieve prices. (300/2 = 150)
"the winners are equally likely to win one of the three prizes..."
This means that of those 150 winners, they will have a 1/3 chance of getting one of the three prices.
There are 150 winners and 1/3 of those will get a book, and 1/3 will recieve gift certificate to a restaurant, 1/3 will recieve a movie ticket. So a third of the 150 winners will recieve a movieticket(150/3=50)
I think i am correct, otherwise someone else will have to correct me
