The median is the middle number when the list is arranged in size order. If there is an even amount of numbers on the list, the median is the mean of the two middle numbers.

   An ordinary die is labeled with numbers from 1 to 6. These numbers are arranged on the die such that the sum of the numbers on opposite faces—called the die constant—always equals 7. Label the faces of a special die with six different prime numbers so that the die constant is as small as possible. Except for 2, all prime numbers are odd. Therefore, 2 cannot be on the prime number die, because then the die constant, K, would be odd for one pair of sides and even for the other two pairs. Thus, all
