[QUOTE="needstatshelp, post: 4520242, member: 489529"] [h2]Homework Statement [/h2] Q: Approximately 16% of the calls to an airline reservation phone line result in a reservation being made. a. Suppose that an operator handles 15 calls. What is the probability that none of the 15 calls result in a reservation? (Give the answer to 3 decimals places.) I have tried 1-.16=.84 (incorrcect) I thought maybe it was not probable for an answer of 0 (incorrect) I also at one point ended up with the answer 0.011 but cannot remember how I got that answer b.What is the probability that at least one call results in a reservation being made? (Give the answer to 3 decimals places.) I would think you would divide 1 by 15. Probable opportunities divided by actual opportunities. But, I am sure I am supposed to use the 16% in this equation somewhere...very stuck. [h2]Homework Equations[/h2] I am new to this and this is my first math class in 25 years so I am not sure what to put here. [h2]The Attempt at a Solution[/h2] for part a: I have tried 1-.16=.84 (incorrcect) I thought maybe it was not probable for an answer of 0 (incorrect) I also at one point ended up with the answer 0.011 but cannot remember how I got that answer for part b I would think you would divide 1 by 15. Probable opportunities divided by actual opportunities. But, I am sure I am supposed to use the 16% in this equation somewhere...very stuck. [/QUOTE]
