What is wrong with the following scenarios? a) If a sample space has two outcomes, then each outcome has probability 0.5. b) If we select a digit 0,1,2,..9, at random the probability of selecting 2 is 0.2 c) If the probability of A is 0.2 and the probability of B is 0.3 then the probability of A and B is 0.5. d) If the probability of A is 0.2, the probability of not A is .5
