Single Maths B Probability & Statistics: Exercises & Solutions 1. QUESTION: Describe the sample space and all 16 events for a trial in which two coins are thrown and each shows either a head or a tail. SOLUTION: The sample space is S = {hh, ht, th, tt}. As this has 4 elements there are 24 = 16 subsets, namely
Question 4: There are 12 red roses, 5 yellow roses and 3 white roses in a vase. Felix takes a rose, at random, from the vase. (a) Write down the probability that he takes a white rose. (b) Write down the probability that he takes a red or a white rose.
Practice and Problem Solving: A/B. Determine the probability of each event. Write impossible, unlikely, as likely as not, likely, or certain. Then, tell whether the probability is 0, close to 0, 1 , close to 1, or 1. 2. 1. randomly picking a blue card from a bag containing all blue cards.
