If you’re asked to compute the probability of getting exactly $k$ successes, you can find it in the table on the right-hand side.

If you’re asked to compute the probability of getting at least $k$ successes, choose Right-sided  and enter the value of $k$.

If you’re asked to compute the probability of getting at most $k$ successes, choose Left-sided  and enter the value of $k$.

If you’re asked to compute the probability that the number of successes is between $N$ and $M$ successes, including $N$ and $M$, choose Interval  and enter the values of $N$ and $M$.

If you’re asked to compute the probability that the number of successes is not between $N$ and $M$ successes, including $N$ and $M$, choose Two tailed and enter the values of $N-1$ and $M+1$. Alternatively, you can compute the probability in the item above, and then take that probability and subtract it from 1.
