3. Based on years of a mild caffeine addiction and a very keen sense of observation, your teaching assistant has determined the probability distribution function of x, the number cars in the drive-through line at 8:00 am to be as follows: X 2 3 f(x) .310 .340 0 .005 1 .025 4 .220 5 .080 (a) Sketch the probability density function for X. (b) Find the probability that on a given day more than 3 cars will be in line. (c) Compute the expected value of the random variable X. Interpret this result. (d) Compute the variance and standard deviation of X. 6 .020
