# cupy.random.geometric¶

cupy.random.geometric(p, size=None, dtype=<class 'int'>)[source]

Geometric distribution.

Returns an array of samples drawn from the geometric distribution. Its probability mass function is defined as

$f(x) = p(1-p)^{k-1}.$
Parameters: p (float) – Success probability of the geometric distribution. size (int or tuple of ints) – The shape of the array. If None, a zero-dimensional array is generated. dtype – Data type specifier. Only numpy.int32 and numpy.int64 types are allowed. Samples drawn from the geometric distribution. cupy.ndarray
