The median is the number in the middle. When you have a even number of numbers, as we do here, we take the mean of the two middle numbers. First put the numbers in ascending order. We have 20 37 49 56 . Since 37 and 49 are the two in the middle we take their mean. 37+49=86 and half of that is 43 so this is the median.

The probability of a prime number in a random pick from the numbers 1-49 is 15 in 49, as there are 15 prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43,and 47) in the range of 1 to 49.
37 x 49 = 1813
