Chapter 4, Problem 3E(choose chapter or problem)
When a certain glaze is applied to a ceramic surface, the probability is 5% that there will be discoloration, 20% that there will be a crack, and 23% that there will be either discoloration or a crack, or both. Let X = 1 if there is discoloration, and let X = 0 otherwise. Let Y = 1 if there is a crack, and let Y = 0 otherwise. Let Z = 1 if there is either discoloration or a crack, or both, and let Z = 0 otherwise.
a. Let \(p_{X}\) denote the success probability for \(X\). Find \(p_{X}\).
b. Let \(p_{Y}\) denote the success probability for \(Y\). Find \(p_{Y}\).
c. Let \(p_{Z}\) denote the success probability for \(Z\). Find \(p_{Z}\).
d. Is it possible for both \(X\) and \(Y\) to equal 1?
e. Does \(p_{Z}=p_{X}+p_{Y}\)?
f. Does Z = X + Y ? Explain.

ANSWER:Answer:
Step 1 of 6:
(a)
In this question, we are asked to find the success probability for and hence .
Certain glaze is applied to a ceramic surface.
Discoloration in surface =
Crack in surface = 20%
There will be either discoloration or a crack, or both in surface = 23%
Let if there is a discoloration in surface, let otherwise.
Let if there is a crack in surface, let otherwise.
Let if there will be either discoloration or a crack, or both in surface, let otherwise.
Hence the success probability for () is .
