24 three digit numbers if repetition of digits is not allowed. 4P3 = 24.If repetition of digits is allowed then we have:For 3 repetitions, 4 three digit numbers.For 2 repetitions, 36 three digit numbers.So we have a total of 64 three digit numbers if repetition of digits is allowed.
How many 4 digit numbers can be formed from the digits 7341 if none of the digits can be repeated?

How many 3 digit numbers can be formed from the digits 24578 if no digits can be repeated?
There are 5*4*3 = 60 such numbers.
How many three digit number contain the digit 2?
There are several ways to answer this. I think this is the easiest: Count the number of three-digit numbers: The first digit can be 1-9; the second and third digits can be 0-9. So, there are 9 choices for the first digit and 10 choices for the second and third digits. This gives you 9 x 10 x 10 = 900 three-digit numbers. Right? Then count the number of three-digit numbers that do NOT contain the digit 2. This is done similarly! Try it! Now, if you think about it, the difference between these two quantities IS the number of three-digit numbers that DO contain a 2, which is what you wanted.
