Suppose X has mass and px(x) = 0 otherwise. a. For A = 2, make a plot
Question:
and px(x) = 0 otherwise.
a. For A = 2, make a plot of the probability mass function.
b. What is the CDF of X, when A = 2?
c. Make a plot of the CDF, when A = 2.
For future reference, this is called a Poisson random variable. You may want to refer to the Math Review for help with the summation of the terms of the form λx / xǃ We will study these random variables more in Chapter 18.
