Could anyone please help me with this problem? Assume that 4 digits are selected at random from the set {1,3,7,8,9} and are arranged in random order.
What is the probability that the resulting 4digit number is less than 8000?

Best ResponseYou've already chosen the best response.0We have a fourdigit number, and we want it to be less than 8000. One way to find the probability would be to look at every possible 4digit number which uses the correct combination of digits, but there's a shorter way to do things.
