Oh, dude, you're hitting me with the math questions, huh? Alright, so to find the number of 5-digit combinations from 1 to 20, you just do 20^5, which is like 3,200,000. So, yeah, there are 3,200,000 possible 5-digit combinations from 1 to 20.

To calculate the number of 5-digit combinations from 1 to 20, we first need to determine the total number of 5-digit numbers possible within this range. Since we are working with numbers from 1 to 20, the smallest 5-digit number would start with 1 (e.g., 10000), and the largest 5-digit number would start with 2 (e.g., 20000). Therefore, the total number of 5-digit combinations from 1 to 20 would be the difference between the largest and smallest 5-digit numbers, plus one (to account for the inclusive range). This gives us 20000 - 10000 + 1 = 10001 combinations.
Well, darling, if you're looking for 5-digit combinations from 1 to 20, there's only one possible combination because there are only four numbers in that range that can make up a 5-digit number. So, the answer is 1. Hope that clears things up for you, honey!
There are 1140 5 digit combinations from 1 to 20. 20 combination 3 computes that.
I am assuming you mean 3-number combinations rather than 3 digit combinations. Otherwise you have to treat 21 as a 2-digit number and equate it to 1-and-2. There are 21C3 combinations = 21*20*19/(3*2*1) = 7980 combinations.
There are 5,461,512 such combinations.

There are 9C2 = 9*8/(2*1) = 36 2-digit combinations.
