I'm having a statistics test on Wednesday. Maybe this will help:
You are looking for X
n= # of people at the RENT rush/lotto.
p=1/---- (using a decimal)
q= whatever is left of P
np= is your mean
square root of npq is your standard deviation
If your standard deviation is 5 or less than than your x, your odds are not good. If it is 5 or more, your odds are better.
If you choose to use the z-score method than you need the positive z-score sheet which you most likely don't have.
Oh-well...
I hope I helped
