If 4 numbers from 1 to 1000 are chosen at random, one at a time, find the probability that they will be all multiples of \(5\).
+2668 I'll give this problem a shot...
There are 1000 x 999 x 998 x 997 options.
There are 200 x 199 x 198 x 197 successes.
So the answer is (200 x 199 x 198 x 197)/ (1000 x 999 x 998 x 997)
