P(0, 3, -2), Q(3, 7, -1) and R(1, -3, -1) are 3 given points. Find vec (PQ)

Mr. A randomly picks 3 distinct numbers from the set {1, 2, 3, 4, 5, 6, 7, 8, 9} and arranges them in descending order to form a three digit number. Mr. B randomly picks 3 distinct numbers from the set {1, 2, 3, 4, 5, 6, 7, 8} and also arranges them in descending order to form a 3 digit number. Q. The probability that A and B has the same 3 digit number is :
