A box contains four cards, each card marked with a number. The numbers are "1", "2", "4", "6". A chance process consists of drawing three cards from the box, one after the other without replacement and computing the value of the range of the three numbers. The range is the largest number minus the smallest number. To illustrate, if the cards drawn are "1", "4", and "2" the outcome will be 4 - 1 = 3, if "2", "4", and...

5. This is a bonus question. You will get extra marks for doing it. Four probabilists are playing a game of cards. Each of them has been dealt a hand of 13 cards from a standard wel shuffled pack of 52 cards. Note that there are 12 pictures cards namely the Jack, Queen and King of each of the four suits (Clubs, Diamonds, Hearts and Spades). Suppose that one of the probabilists is picked uniformly at random. (a) What is...
