right away looking at the question and the answers I could tell which is which, all i did was add 15 and 2 and I saw that none of them were close to it besides D so i added 3^15-1 and got 17.

Nd then hes has to do 15 questions so number of ways of doing it=3x3x3x....fifteen times

  • imqwerty
But then there is a case where the kid leaves the paper empty :) so we give him a - 1 cause we will not consider that he attempted the paper. So we get the answer - 3^15-1

that made sense in your justification of taking one away from the 3^(15) you know because if he doesn't answer any of them then it is not really consider an attempt but I have seen people attempt tests and write nothing on it except a drawing :p

huh I always thought okay was the proper word for slang ok. But ok is actually okay. Like I think they use the word ok more actually. And ok is consider its full form. It just also has different forms that are used such as okay.

I just realize I completely missed something in your question @mathmath333 oh you know what they thingy does say how can the person attempt one or more questions anyways so that part wasn't a guessing thing if it said how can the person attempt 0 or more questions then it would have been 3^(15)
