At a construction project, the amount of material used in a day's construction is either 100 units or 200 units, with the corresponding probabilities of 0.60 and 0.40. If the amount of material required in a day is 100 units, the probability of shortage of material is 0.10, whereas if the amount of material required is 200 units, the probability of shortage of material is 0.30. What is the probability of shortage of material in a given day?
