Probability Quiz

Question 1 If I throw a fair dice 30 times, how many FIVES would I expect to get?

Question 2 A bag contains 12 marbles; 5 are RED, 3 are WHITE and 4 are BLUE. When a marble is picked at random, what is the probability of getting one that is not WHITE?

Question 3 A coin is tossed two times. List all the possible outcomes.

Question 4 In a raffle 400 hundred tickets are sold. If you have bought 5 tickets and your father has bought 3 tickets, what is the probability that either you or your father will win the first prize?

Question 5 When you throw a fair dice, what is the probability of getting a factor of 6?

Question 6 A spinner has the numbers 1, 3, 5 and 7. For this spinner, state two events that are both Mutually Exclusive and Exhaustive.

Question 7 Two fair dice are rolled. The sum of the two numbers uppermost is noted. What is the probability of this sum being less than 4?

Question 8 A biased coin has a probability of ⅔ of obtaining heads when thrown. The coin is tossed twice. What is the probability of obtaining a tail followed by a head?

Question 9 A bag contains 3 BLUE balls and 5 RED balls. One ball is taken out at random, the colour is noted and then put back in the bag. A second ball is selected at random. What is the probability of getting two balls of different colours?

Question 10 A bag contains 4 YELLOW and 5 GREEN balls. A ball is selected at random and its colour is noted. It is not put back in the bag. A second ball is selected at random. What is the probability of obtaining two GREEN balls?
