Question

During the summer months, a rental agency keeps track of the number of chain saws it rents each day during a given period and X denotes the number of saws rented per day. Describe a probability distribution, if it is probability distribution, find the mean, variance, and standard deviation for the probability distribution. x 0 1 2 P(x) 0.5 0.33 0.17 2. If X is binomially distributed with 6 trials and a probability of success equal to ¼ at each attempt. What is the probability of exactly 4 success? Also find the parameter mean, variance and standard deviation. 3. Find a) P(z < 2.37) b) P(z > 1.82) c) P(-1.18 < z < 2.1)
