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.
a. let px denote the success probability for x. find px. b. let py denote the success probability for y. find py. c. let pz denote the success probability for z. find pz. d. is it possible for both x and y to equal 1? e. does pz = px + py? f. does z = x + y? explain.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
