Graph of a probability distribution

WebThe graph of a Bernoulli distribution helps to get a visual understanding of the probability density function of the Bernoulli random variable. The graph shows that the probability of success is p when X = 1 and the probability of failure of X is (1 - p) or q if X = 0. WebThe notation for the uniform distribution is. X ~ U ( a, b) where a = the lowest value of x and b = the highest value of x. The probability density function is f ( x) = 1 b − a for a ≤ x …
