It Doesn't Fit The Table!
Query [from KN]: A variable X has a Binomial Distribution, where n=25 and p=0.8. I'm meant to work out P(X>15), but my Binomial Table doesn't list p-values above 0.5?
Response: As this is a Binomial Distribution, while you are counting 'success' you are counting 'failure' also at the same time.
So, think of Y~B(25,0.2) instead and look up your tables for P(Y<10).
