Asked by desperatestudent
A student taking an examination is required to answer exactly 10 out of 15 questions.
I think i'm supposed to use combination right? Order does not matter? Because it can be any choice of the 10 questions? I am usually horrible deciphering what to do but I think with permutation I must look out for the keywords "arrange" or "order".
