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
