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
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.
