Reply:Assuming that for each question you are starting with a standard shuffled deck of 52 cards, and a card is picked at random:





a) 4/52 = 7.69%


b) 13/52 = 25%


c) 8/52 = 15.38%


d) 39/52 = 75%


e) 26/52 = 50%


f) 48/52 = 92.3%


g) 48/52 = 92.3%


i) 52/52 = 100% (50% for either color)
