For the chapter 9 section of review, numbers 45-52, will we be expected to do out the whole nCr part by hand? Or will we be allowed to do that part in our calculators and expand the rest to save time? Thanks!
Oh and Mawra, we do not get a formula sheet for the final exam…
Serena,
On your nCr question, yes…. but remember. 4C0 + 4C1 + 4C2 + 4C3 + 4C4 = 2^4, for example. More generally, nC0 + nC1 + nC2 + … + nC(n-1) + nCn = 2^n. You can just write “2^n” and that would be sufficient work.
Thanks for replying to Mawra.
Hope this helps,
Mrs. Corricelli
