A child has 11 stuffed animals. How many ways can she choose 3 animals to take along with
her on vacation?

165 ways

Step-by-step explanation:

That notation is read "n choose m", and it indicates the number of ways one can choose m objects from a collection of n objects, if we don't care about "order".

So in your case we have

which in terms of a "factorial" notation is

11! / 3! × (11-3)!

11×10×9×8! / 3! × 8!

990 / 3

165

I've just assumed that you know what factorial means. If you don't, feel free to ask me.

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

probability for j is 1/4

while

a is 1/6
