Probability, p. is a quantitative measure of how likely an event is to occur. Each of the subsequent questions details the likelihood of an event occurring. For each one, choose the value of p that best corresponds to that likelihood. The event is impossible and never occurs. Op=0.99 Op = 0 O p = 0.01 O p = 0.6 Op=1 Op= 0.3 The event is certain and always occurs. Op=0.01 Op=1 Op=0 Op = 0,3 Op=0,99 O p = 0.6...

(17) Which of the following statements is true? (1) The set of all possible events of an experiment is called the sample space, S. (2) If an experiment is performed more than once, one and only one event can occur. (3) If two events A and B are mutually exclusive, then P(AUB) = 0. (4) A simple event is the outcome observed on a single repetition of an experiment.
