How to read this table
- Find the block for your number of trials n.
- Go to the row for x and the column for p.
- The cell is P(X = x). Add cells to get the probability of a range of values, or use the cumulative table.
- 0+ means a probability that is positive but below 0.00005; 1− means one that is below 1 but above 0.99995.
Worked example
In a Phase II trial of 10 patients where the true response rate is 20%, the chance of exactly 2 responses is in the n = 10 block, row x = 2, column p = .20: 0.3020. The chance of no responses at all is 0.1074.
This is the calculation behind single-arm Phase II designs such as Simon's two-stage design, which choose sample sizes and response thresholds from binomial probabilities.

Formula and how the values were computed
Each cell is computed exactly from the binomial formula and rounded to four decimals.
Frequently asked questions
What are the conditions for a binomial distribution?
A fixed number of trials n, two outcomes per trial, the same probability of success p on every trial, and independent trials.
What if n is larger than 20?
Use the calculator above, which handles any n. When np and n(1 − p) are both at least about 10, the normal approximation with mean np and variance np(1 − p) also works well.
