@GoldEverything Could you help me out with this? Thanks! Joel owns 12 shirts and is selecting the ones he will wear to school next week. How many different ways can Joel choose a group of 5 shirts? (Note that he will not wear the same shirt more than once during the week.) a. 17 ways b. 792 ways c. 60 ways d. 95,040 ways
I think the answer is 792.
Is that right?
correct if you would mind showing me some work so i can approve
Okay I'll start writing out the work!
12*11*10*9*8*7*6*5*4*3*2*1 ______________________________ 7*6*5*4*3*2*1*5*4*3*2*1 Then you can cancel the 7 and lower at the top, and the bottom, and you're left with: 12*11*10*9*8 _______________ 5*4*3*2*1 And you get 95040 _______ 120 And you get 792.
it seems that it is all there so good job
Okay, thanks!
