To calculate the number of 4-number combinations from 1 to 20, we can use the formula for combinations, which is nCr = n! / (r!(n-r)!), where n is the total number of items and r is the number of items to choose. In this case, n = 20 and r = 4. Plugging these values into the formula, we get 20C4 = 20! / (4!(20-4)!) = 4845. Therefore, there are 4845 different 4-number combinations possible from the numbers 1 to 20.

How many 5 digit combinations are there from 1-20?
To find the number of 5-digit combinations from 1 to 20, we first calculate the total number of options for each digit position. Since the range is from 1 to 20, there are 20 options for the first digit, 20 options for the second digit, and so on. Therefore, the total number of 5-digit combinations is calculated by multiplying these options together: 20 x 20 x 20 x 20 x 20 = 3,200,000 combinations.
How many combinations of amino acids do enzymes have?
Enzymes are proteins composed of 20 different amino acids, so the number of possible combinations of amino acids in an enzyme is vast, with 20 amino acids at each position in the protein chain. The total number of potential combinations is calculated as 20 raised to the power of the number of amino acids in the enzyme.
