Best ResponseYou've already chosen the best response.1Focusing on just 3, 4, 5, 6 for the first digit, we have 4 choices for slot 1 That leaves 51 = 4 digits left over for slot 2 and 52 = 3 digits for slot 3 4*4*3 = 16*3 = 48 different 3 digit numbers that start with 3,4,5, or 6  if we have 2 in the first slot, then we can't have 3 or 4 in the second slot. Only 5 or 6 can be picked. That leaves 3 digits left over 1*2*3 = 6 there are 6 different permutations that start with 2 and are larger than 250 they are... 253 254 256 263 264 265  in total, there are 48+6 = 54 different numbers that are between 250 and 700
