In: Statistics and Probability
In a certain lottery you select seven distinct numbers from 1 through 39, where order makes no difference. How many different ways can you make your selection?
Here order does not matter. So we can use combination.
Number of different ways you can make your selection
n! = n*(n-1)!
n!= 1*2*3*.....n
= 15380937
Number of different ways you can make your selection = 15380937
