Chapter 7, Problem 7-61(choose chapter or problem)
A lot consists of N transistors, and of these M (M N) are defective. We randomly select two transistors without replacement from this lot and determine whether they are defective or nondefective. The random variable Determine the joint probability function for X1 and X2. What are the marginal probability functions for X1 and X2? Are X1 and X2 independent random variables?
