WebIn probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the last event. It is named after French mathematician … WebDefinition 4.3. 1. A random variable X has a uniform distribution on interval [ a, b], write X ∼ uniform [ a, b], if it has pdf given by. f ( x) = { 1 b − a, for a ≤ x ≤ b 0, otherwise. The uniform distribution is also sometimes referred to as the box distribution, since the graph of its pdf looks like a box. See Figure 1 below.
