So the density function of T is (1) f(t) = Suppose the times between arrivals are independent. The bank would like to know the following. a. The probability that the second customer arrives after 4 minutes from now. b. The probability that exactly one customer arrives within the next 4 minutes. Let. T1 = time (in min) until the next customer ...

Marginal probability density functions: The pdf's of S and T separately are sometimes called the marginal pdf's. Proposition 2. Let S and T be continuous random variables with joint density function fST(s, t) and individual density functions fS(s) and fT(t). Then (9) fS(s) = (10) fT(t) = Proof. The density function fS(s) of S is the only ...
