' ' The outcome of one trial does not affect the probability of success on any other trial. \\ One outcome is less likely to happen than the other outcomes. The outcome of one trial affects the probability of success on any other trial. " One outcome is more likely to happen than the other outcomes. 17. DETAILS BBBASICSTAT8 7.3.018.MI.S.

MY NOTES If two events are mutually exclusive, can they occur concurrently? Explain. Yes. By definition, mutually exclusive events can occur together. No. By definition, mutually exclusive events cannot occur together. No. Two events will never occur concurrently. Yes. Any two events can occur concurrently.20 DETAILS BBBASICSTAT8 7.3.015.MI.S.

MY NOTES A recent survey of 1030 U.S. adults selected at random showed that 683 consider the occupation of firefighter to have very great prestige. Estimate the probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.22. DETAILS BBBASICSTAT8 7.6.008.S. MY NOTES In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities. Do you try to pad an insurance claim to cover your deductible? About 35% of all U.S. adults will try to pad their insurance claims! Suppose that you are the director of an insurance adjustment office. Your office has just received 122 insurance claims to be processed in the next few days. Find the following probabilities. (Round your answers to four decimal places.) LA USE SALT (a) half or more of the claims have been padded (b) fewer than 45 of the claims have been padded (c) from 40 to 64 of the claims have been padded (d) more than 80 of the claims have not been padded23.
