Materials/supplies are delivered from two different distributers into a manufacturing site. In each day there is a 30% chance of delivery from distributer A, 40% chance of delivery of distributor B and 30% chance of no delivery at all independent of any other day. We can assume that the delivery from the two distributers are also independent. Find the probability that there are 5 deliveries in one week (7 days). b. If in day 2 there was a delivery from distributer A, find the average time of receiving two more deliveries from this distributer. а. c. If in day 2 there was a delivery from distributer A, find the average time of receiving two more deliveries. d. X is the number of items delivered by distributor A before distributer B delivers 3 items. Find the PMF of X.
