X and Y are independent random variables with the following joint probability distribution:    for 1 < x < 6, 2 < y < 4        This copywritten question is part of an exam or quiz at Arizona State University and may not be posted to Chegg.com or any other online site.   Determine

Random variable X has the discrete uniform pmf for x = 0, 1, 2 and random variable Y has the discrete uniform pmf for y = 1, 2, 3, 4.  X and Y are independent.  This copywritten question is part of a quiz or exam at Arizona State University.

Recall that pX|Y(x|y) is the same as saying P(X = x|Y = y) and recall that px(x) is the same as saying P(X = x). When random variables X and Y are independent, pX|y(x|y) = pX(x).

Chattin.   If you want to determine the probability that two or fewer in this sample show a sign, which distribution will you need to use?  Select the very best answer.

You should be familiar with this example in Chapter 2 of the text.  H is the event a wafer contains high contamination and C is the event that the wafer is in the center of the tool: Contamination Center Location Edge Location Total Low 514 68 582 High 112 246 358 Total 626 314  This copywritten question is part of a quiz or exam at Arizona State University.  It may not be posted or reproduced without the permission of Dr. L.
