- Flexible Work Hours In a recent survey, people were asked whether they would prefer to work flexible hours----even when it meant slower career advancement----so they could spend more time with their families. The figure shows the results of the survey. What is the probability that three people chosen at random would prefer flexible work hours?arrow_forwarda What is meant by an experiment? Sample space? b What is an event? c Define the probability of an event E in a sample space S in which all outcomes are equally likely. d What is the probability of the complement of E? e If a coin is tossed three times, what is the probability of getting all heads? At least one tail?arrow_forward
