Help with my stat homework? Would appreciate answers with the work shown, not really sure how to work the problems
damn, i only know how to do these with a calculator because that's how my book showed everything
if you're allowed to use a ti84 or a ti36 i could show you how to do most of these

How do I do them with a ti84?
>>150865
for the first page:
a) it gives you the probabilities for 0 through 3, so to find the probability for at most 1, you'd need to add together the p(x) for 0 and 1
b) i believe this should be 0% because the probabilities add up to 100%, leaving no probability for the number to not be 0 - 3
c and d) put x into list 1, p(x) into list 2, run 1varstats using l1 for data and l2 for frq. (c) will be the x with a line on top and (d) will be the sigma
i'm reasonably certain that's how those are done. also (2) on the second page you just punch in 22 nCr 6, or nCr(22,6)
