Each of the digits 0-9 is written on a slip of paper, and the slips are placed in a hat. If 5 slips of paper are selected at random, determine the probability that the 5 numbers selected are greater than 3.
The number of possible sets that could be drawn from choosing any 5 of the 10 numbers = 10 C 5 = 252
And the number of possible sets drawn from ( 4,5,6,7,8,9) = 6C5 = 6
So
P( that all 5 numbers drawn are > 3) = 6 / 252 = 1 / 42
