The number of orders per week for a certain item is thought to have the Poisson pmf.  A sample of 100 weeks of orders are reviewed, and the observed values were: 22 weeks in which there were 0 orders 38 weeks in which there was 1 order 31 weeks in which there were 2 orders 9 weeks in which there were 3 orders This copywritten question is part of a quiz or exam at Arizona State University.

A transmitted bit can have high, moderate, or low distortion with probabilities 0.03, 0.12, [c]. respectively.  Three bits are transmitted and the amount of distortion in each is independent.  This copywritten question is part of a quiz or exam at Arizona State University.

A transmitted bit can have high, moderate, or low distortion with probabilities 0.03, 0.12, and 0.85, respectively.  Three bits are transmitted and the amount of distortion in each is independent.  Let X be the number of bits with high distortion and Y be the number of bits with moderate distortion.
