This is not a draft for review but a question that is in great need to be answered. It is concerning the Discrete Probability Distribution.

'''Q : Residents in an inner city area are concerned about drug dealers entering their neighborhoods. Over the past 14 nights, they have taken turns watching the street from a darkened apartment. Drug deals seem to take place randomly at various times and locations. On average about three per night. they reported the matter to the police but the police requested for five videos of the deals to take matters in their hands. Renting of a video camera is $75 the first night and $40 for each additional nights. the neighborhood wants to know the probability of taping at least five drug deals on a given number of nights.

(a) Which of the probability distributions might be helpful? (b) What assumptions under such probability distribution would you have to make? (c) If the residents tape for two nights, what is the probability they will film at least five drug deals? (d) For how many nights must the camera be rented so that there is at least .90 probability that five or more drug deals will be taped?
