A single card is chosen at random from a shuffled standard fifty-two card deck (no jokers). Find the following probabilities: 1) What is the probability that the value 6 shows up on at least on of the rolls? P(D1=6∪D2=6) 2) What is the probability that the value 6 show up on exactly one of the rolls? P((D1=6∪D2=6)∖(D1=6∩D2=6)) 3) What is the probability (as a rational number is a/b format) that the value sum D1+D2 is 30 ? 10 ? 23 ? P(D1+D2=30) P(D1+D2=10) P(D1+D2=23)
