Question

Diserete Distribution& Binomial Distribution Date: Team 1. Determine if the distribution is valid or not for each of the following discrete distributions .2 .2 .2 2. The following is the data collected from a city regarding the f# of car accidents per day due to drunken driving in history. Since the data comes from a long time period, we assume this represents the distributions of # of car accidents per day due to drunken driving for the city. # of car accidents, X | 0 15 05 02 (a) Determine probability of having one accident (b) Is the shape of the distribution of # of Car Accidents symmetric, skewed to right or skewed to left? (c) Determine probability of having more than 3 accidents per day (d) Determine probability of having at most 2 accidents per day. (e) Determine probability of having at least S accidents (f) What is the expected # of accidents per day?
