Gregory buys a bag of cookies that contains 7 chocolate chip cookies, 5 peanut butter cookies, 8 sugar cookies and 8 oatmeal cookies. What is the probability that Gregory reaches in the bag and randomly selects an oatmeal cookie from the bag, eats it, then reaches back in the bag and randomly selects a peanut butter cookie?

Fiona walks from her house to a bus stop where she gets a bus to school. Hertime, W minutes, to walk to the bus stop is normally distributed with W-N (12^3) Fiona always leaves her house at 07:15. The first bus that she can get departs at 07:30. a) Find the probability that it will take Fiona between minutes andminutes to walk to the bus stop. The length of time, minutes, of the bus journey to Fiona’s school is normallydistributed with B-N (50, σ^2) . The probability that the bus journey takes less than60 minutes is 0.941. b) Find σ c) Find the probability that the bus journey takes less than 45 minutes. If Fiona misses the first bus, there is a second bus which departs at 07:45. Shemust arrive at school by 08:30 to be on time. Fiona will not arrive on time if shemisses both buses. The variables W and B are independent. d) Find the probability that Fiona will arrive on time This year, Fiona will go to school on 183 days.e) Calculate the number of days Fiona is expected to arrive…

Suppose the probability that a male develops some form of cancer in his lifetime is 0.4573. Suppose the probability that a male has at least one false positive test result (meaning the test comes back for cancer when the man does not have it) is 0.51, and that this probability is independent of the probability that a male will develop cancer in his lifetime. • C = a man develops cancer in his lifetime• F = a man has at least one false positive Part (a) Construct a tree diagram of the situation. P(C) = P(F | C) = P(F | C' ) If a test comes up positive, based upon numerical values, can you assume that man has cancer? Justify numerically and explain why or why not. -You cannot assume the man has cancer because there is not enough information given. -You cannot assume the man has cancer because there is a 51% chance that the test is false. -You cannot assume the man has cancer because both the probability of developing cancer in his lifetime and the probability of…
