How many combinations of 5 numbers are there for 1-30?

Answer 1

To calculate the number of combinations of 5 numbers chosen from 1 to 30, we use the combination formula which is nCr = n! / (r!(n-r)!). In this case, n = 30 and r = 5. Plugging these values into the formula, we get 30! / (5!(30-5)!) = 142,506 total combinations.

Answer 2

Well, darling, there are a whopping 142,506 combinations of 5 numbers that can be selected from a range of 1-30. So, good luck trying to win the lottery with those odds!

Answer 3

The number of combinations of r numbers out of n is

nCr = n!/[r!*(n-r)!] where n! = 1*2*3...*n

So here n = 30, r = 5 which gives

30*29*28*27*26/(5*4*3*2*1) = 142,506
