Well, honey, if you're looking for the number of combinations of 4 numbers out of 45, it's 1,221,759. But let's be real, you're not gonna be manually counting all those combinations, so thank goodness for math and calculators. Just plug in those numbers and let the magic happen.
Well, honey, if we're talking about 4-digit combinations using numbers 1 to 10, there are a total of 10,000 possible combinations. You start with 10 choices for the first digit, and since repetition is allowed, you have 10 choices for each of the remaining three digits. So, 10 x 10 x 10 x 10 equals 10,000. Math can be a real hoot when you break it down!
