Question 19

What is the probability of winning a raffle if 500 tickets are sold and you buy 5 of them?

P(win)

P.O/T.P.O

5/T.P.O

5/500

1/100

0.01*100

1%

Question 20

A class of 25 students has 15 girls and10 boys. If one student is chosen at random, what is the probability it is a girl?

P(girl)

P.O/T.P.O

15/T.P.O

15/25

3/5

0.6*100

60%

Question 21

There are 26 letters in the alphabet. What is the probability that a letter chosen at random is in the word MATHEMATICS?

P(mathematics)

P.O/T.P.O

8/T.P.O

8/26

4/13

0.307*100

30.7%

HINT: Do not count letters that are repeated in the word mathematics. If you do that,the answer would be 11/26 0.423 42.3%.

My own question

You go to a circus with 44 clowns. 12 don't talk and 32 talk. If a clown was chosen at random, what is the probability of a non-talking clown being chosen?

The answer

P.O/T.P.O

12/T.P.O

12/44
