Webb13 sep. 2024 · Question In Numpy, what does the np.random.binomial() function return? Answer The function returns a list of samples from a binomial distribution based on the inputted parameters when calling np.random.binomial(n, p, size). For example, # n = 500 (samples or trials) # p = 0.5 (probability of success) # size = 10000 (number of … Webbnumpy.random.normal# random. normal (loc = 0.0, scale = 1.0, size = None) # Draw random samples from a normal (Gaussian) distribution. The probability density function of the normal distribution, first derived by De Moivre and 200 years later by both Gauss and Laplace independently , is often called the bell curve because of its characteristic shape …
