The HP30b doesn't have a builtin function for that. It has a builtin function for the cumulative distribution function (CDF) value, which is the probability of k or fewer successes. The answer for that is 0.7361 (73.61%). Well, you could use the builtin binomial CDF to calculate for n=10, p=0.1, k=0, store that in a memory, calculate for n=10, p=0.1, k=1, and subtract the previously stored value, but that is cumbersome and error prone. It would be easier to use the PMF formula you already know. — Ian Abbott
