# involving the construction of a number from a set of digits. Assume that 3 digits are selected at random from the set {2,3,6,7,9}{2,3,6,7,9} and are arranged in random order.

involving the construction of a number from a set of digits. Assume that 3 digits are selected at random from the set {2,3,6,7,9}{2,3,6,7,9} and are arranged in random order.

What is the probability that the resulting 3-digit number is less than 900?
