Answer:Answer = 1

Step-by-step explanation:If you’re seeing these problems as part of your study of statistics, you should know that

C(n, k) = n!/(k!x(n-k)!)

where the “!” indicates the factorial, the product of all positive integers less than or equal to the given one.

Then C(7, 7) = 7!/(7!x0!) = 1/0!

You are supposed to know also that 0! u2261 1, so C(7, 7) = 1.

This is the number of ways you can choose 7 objects from a pool of 7 objects without regard to order. (You can do it one (1) way: choose all of them.)

The appropriate choice is …
