cupynumeric.random.binomial(n, p, size=None)#

Draw samples from a binomial distribution.

Samples are drawn from a binomial distribution with specified parameters, n trials and p probability of success where n an integer >= 0 and p is in the interval [0,1]. (n may be input as a float, but it is truncated to an integer in use)

Parameters:

n (int) – Parameter of the distribution, >= 0. Floats are also accepted, but they will be truncated to integers.
p (float) – Parameter of the distribution, >= 0 and <=1.
size (int or tuple of ints, optional) – Output shape. If the given shape is, e.g., (m, n, k), then m * n * k samples are drawn. If size is None (default), a single value is returned.

Returns:

out – Drawn samples from the parameterized binomial distribution, where each sample is equal to the number of successes over the n trials.

Return type:

ndarray or scalar
