Guys it's time to stretch their brains, I came across this question on the homework help site!
You just got a free ticket for a boat ride, and you can bring along 2 friends! Unfortunately, you have 5 friends who want to come along.
How many different groups of friends could you take with you?
Need response asap! What are the options?
We can choose any 2 of the 5....so....the number of possible groups is
C(5,.2) = 10 different groups
That's not a realy hard question. I didn't stretch my brain at all.
