Two hundred fifty tickets for a draw were sold.
One ticket, drawn at random, wins the prize.
a) Joe purchased 1 ticket.
What is the probability Joe will win?
b) Maria purchased 10 tickets.
What is the probability Maria will win?
c) Ivan purchased 25 tickets.
What is the probability Ivan will not win?
Express each probability three ways.
+738 a) there's 1 ticket out of 250, so the answer is \(\boxed{\frac{1}{250}=0.4\%=0.004}\)
b) there's 10 tickets out of 250, so the answer is \(\boxed{\frac{1}{25}=4\%=0.04}\)
c) there's 25 tickets out of 250, so the answer is \(\boxed{\frac{1}{10}=10\%=0.1}\)
