PROBLEM 4.2 (pg 63, #17) Let A denote the event that the next request for assistance from a statistical software consultant relates to the SPSS package, and let B denote the event that the next request is for help with SAS. Suppose that P(A) -0.25 and P(B)-0.65. Assume that any request for help never relates to two or more packages simultaneously. Note: since P -0.9, which is less than 1, there are clearly other packages for which help is requested....
