There are 8 containers arranged on on a ship's deck in a single row.. The containers are of two different types, two of type A and 6 of type B. The containe of type A are supposed to be placed in the first 2 spots but since they are randomly placed some type B containers may preceed them. Let X be the numb of type B containers that preceed the first type A container. Find the probability function f(x) of X. You may use symbols ()+-/^ and preview your formula using they symbol f(x) =
