Probability of A and B both occuring: P(AB), Probability that A or B or both occur: P(AB), Probability that A or B occurs but NOT both: P(AB), Probability of neither A nor B occuring: P((AB)'), Probability of event that does not occurs P(A'). Design A EMV= 70%*[ (-1.000.000 cost design A) +(- 7.500.000 cost production ) + (59.000*150=8.850.000 revenue)]+ 30%* [ (-1.000.000 cost design A) +(- 7.500.000 cost production ) + (64.000*150=9.600.000 revenue)= 575 Well, if the probability of throwing a five on one dice is 16.6 per cent, you might assume that it's twice as likely (33.3 per cent) to happen when doubling the number of dice. This means that the probabilities remain essentially constant throughout a series of 'events' - flips of the coin or throws of the dice. Your reasoning only works when the sum S is a real number and does not continue on to infinity. The next time you pull one out the probability will be 1/6. The Daytona 500 runs 40 race cars.
