6. On Tuesday, the weather forecaster says that there is a 40% chance of snow on Wednesday and a 50% chance of snow on Thursday. The forecaster also says that there is a 10% chance of snow on both Wednesday and Thursday. Use a Venn Diagram to determine the probability that there will be snow on Wednesday or on Thursday. (3 marks) Applied 40S Name: 7. Bonita has six identical red marbles and ten identical blue marbles in a paper bag. She pulls out one marble at random and then another marble, without replacing the first marble. Determine the probability that she pulls out a pair of red marbles. (2 marks) 8. A die is rolled twice. Determine the probability that the first roll is greater than 5 and the second roll is less than 4. (3 marks) 9. Anna's school is holding a chocolate bar sale. For every case of chocolate bars sold, the seller receives a ticket for a prize draw. Anna has sold eight cases, so she has eight tickets for the draw. At the time of the draw, 130 tickets have been entered. There are two prizes, and the ticket that is drawn for the first prize is returned so it can be drawn for the second prize. Determine the probability that Anna will win both prizes. (3 marks) 10. Each day, Julia's math teacher gives the class a warmup question. It is a truefalse question 20% of the time and a multiplechoice question 80% of the time. Julia gets 70% of the truefalse questions correct, and 90% of the multiplechoice questions correct. Julia answers today's question correctly. Using a tree diagram determine the probability that the question was a multiplechoice question. (4 marks) 6.
