Two variables control a cat's desirability, d, as a pet, cuteness, c and indifference, i. You propose that the following equation can be used to determine how much you want to own a particular cat, d = c x i , where c is the cuteness of the cat rated from 1-10 and i is the indifference of the cat to your existence rated from 1-10. In this rating, the best possible cat would earn an 100 and the worst a 1.

You rank cat adoption catdidates as so:

Cat Cuteness Cuteness Uncertainty Indifference Indifference Uncertainty
Meowcapone 3 ±1 2 ±2
Catsanova 4 ±3 8 ±4
Luke Skywhisker 9 ±1 5 ±5
Fuzz Aldrin 6 ±2 6 ±2

You can be absolutely certain that Catsanova is a better cat than Meowcapone.

a. True
b. False

Aprisoner is trapped in a cell containing three doors. the first door leads to a tunnel that returns him to his cell after two days of travel. the second leads to a tunnel that returns him to his cell after three days of travel. the third door leads immediately to freedom. (a) assuming that the prisoner will always select doors 1, 2 and 3 with probabili- ties 0.5,0.3,0.2 (respectively), what is the expected number of days until he reaches freedom? (b) assuming that the prisoner is always equally likely to choose among those doors that he has not used, what is the expected number of days until he reaches freedom? (in this version, if the prisoner initially tries door 1, for example, then when he returns to the cell, he will now select only from doors 2 and 3.) (c) for parts (a) and (b), find the variance of the number of days until the prisoner reaches freedom. hint for part (b): define ni to be the number of additional days the prisoner spends after initially choosing door i and returning to his cell.
