Question

17. Find the indicated probability. Round to the nearest thousandth. (I point) A study conducted at a certain college shows that 55% of the schoors graduates find a job in their chosen field within a year after graduation. Find the probability that among 7 randomly selected graduates, at least one finds a job in his or her chosen field within a year of O 0.550 O 0.996 0985 00.143

Answer 1

17)

P(at least one find am job)=1-P(none find a job)=1-(1-0.55)⁷ =0.996

18)

P(upstate airline and on time)=43/87

19)

P(at least 1 year)=P(male)*P(at least 1 year|male)+P(female)*P(at least 1 year|female)

=(2/5)*0.67+(3/5)*0.73=0.71

20)

P(on time |upstate)=43/48

21)

8/13

22)

8/12=2/3

23)

11/20

24)

3/19
