Probability Review B Saputo Name __________________________ Period ______ Date __________ Show all your work. If you can leave it as a fraction, leave it reduced! Calculators are ok and so is the formula sheet. Two dice are rolled and the results are multiplied together. Draw a 2D table of outcomes to display the possible results. Hence determine the probability that the resulting value is: 1 Less than 30 a square number. If I buy 5 tickets in a 200 ticket lottery, and 3 prizes are drawn for winning tickets without replacement, determine the probability that I will win: the first 2 prizes at least two of the first 3 prizes. If A spinner has 5 areas. What is the expected value of a spin? How much would I charge if I want to make an average of $2? On any one day in April, there is a 21% chance of rain and 46% chance of being windy. Draw a tree diagram showing the probabilities of wind or rain on a particular day. Hence determine the probability that on a particular day there will be: rain and not wind rain or wind. Wind, given that it’s rainy. What would happen if wind was dependent on the rain?
