The graph shows that U.S. smokers have a greater probability of suffering from some ailments than the general adult population. Exercises 5758 are based on some of the probabilities, expressed as decimals, shown to the right of the bars. In each exercise, use a calculator to determine the probability, correct to four decimal places. Probability That United States Adults Suffer from Various Ailments Tobacco-Dependent Population General Population 0 Probability 0.05 0.10 0.15 0.20 0.25 0.30 Depression Frequent Hangovers Anxiety/Panic Disorder Severe Pain 0.28 0.12 0.20 0.10 0.19 0.08 0.14 0.07 Source: MARS 2005 OTC/DTC Pharmaceutical Study If the probability an event will occur is p and the probability it will not occur is q, then each term in the expansion of (p + q) n represents a probability. The probability that a smoker suffers from depression is 0.28. If five smokers are randomly selected, the probability that three of them will suffer from depression is the third term of the binomial expansion of (0.28 + 0.72)5 . 2TQDCDKNKV[C UOQMGTUWHHGTU HTQOFGRTGUUKQP 2TQDCDKNKV[C UOQMGTFQGUPQV UWHHGTHTQOFGRTGUUKQP UOQMGTU CTGUGNGEVGF What is this probability?
