There are 6 different colored kittens at the pet store (brown, white, black, calico, orange, and gray). If Annie's family wants to take 2 of them home, how many different combinations of kittens can her family choose from?
Need help can someone explain this to me
Well you have the formula. The question tells you you need to find the combination. Do you know what numbers to plug into the variables in the equation?
no
n is the number of choices available. r is the number of choices made. In this question you have a choice of 6 kittens, you are choosing 2.
but what is it a combination or a permutation
"how many different combinations" Also, from http://www.mathsisfun.com/combinatorics/combinations-permutations.html "If the order doesn't matter, it is a Combination.If the order does matter it is a Permutation."
so it's a combination
That's what it seems like to me.
