S2 Poisson Distribution
... For a Poisson distribution to be valid, the mean and variance need to be equal or very close. In this situation they are not close and so a Poisson distribution would not be a likely model. ...

... Defn: A random variable is a variable whose values are determined by chance. We will denote a random variable by a capital letter, such as X, and denote particular values of the variable by the corresponding lower case letter, x. Thus we read P(X = x) as: “the probability that the random variable X ...

The event that a seat is not available occurs if and only if X = 21, and P (X = 21) = (.98)21 = .6543. The expected loss of the operator due to overbooking is (0)P (X < 21) + (100)P (X = 21) = (100) ...
