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...
