How many 1-digit numbers are there in the first space?
Since the number must be a positive interger, we exclude 0 from our answer. So we have 5 1-digit numbers. Since it must be a 2-digit number, we cannot include 0 infront, so we can choose only 5 numbers for the first space.
How many possibilities are there for 3 blank numbers?
The digit 5 is also not a possibility). Thus, 4 possibilities for blank 3. Now, using multiplication principle for all three blanks : 8*9*3 = 288. I think you meant 8*9*4 = 288 …but otherwise, you are correct!
How many permutations of a number that starts with 3?
If a number starts with 3, then all numbers are greater than 30k. For example, the smallest number starting with 3 is 31245. So you only need subtract the numbers starting with 1 or 2.
