A random variable is a rule that assigns a numeric value to every possible outcome in a sample space. Random variables may be discrete or continuous in nature. A random variable is discrete if it assumes only discrete values within a specified interval.
PMT 8 5 Customers arrive at a shop at a constant average rate of 2.3 per minute. (a) State another condition for the number of customers arriving per minute to have a Poisson distribution. [1] It is now given that the number of customers arriving per minute has the distribution Po2.3....
