On a summer day it says that the probability that a hot dog stand will sell out of hot dogs is 3/5

find at least 70 of 100 days the hotdogs are sold out

I used 1-Binomcdf(100, (3/5), 70) then this gives me an answer that is not a choice.

Results 1 to 5 of 5

I don't own any of these calculators, so I had no idea what that meant.

The most scientific one I use is a TI-30.

I had a fancier one that did all these percentiles, but I gave that to a grad student last year as a graduation gift.

I just googled binomial calculator and came across

Binomial Probability Calculator

These can be found all over the net.
