Miguel’s steps in evaluating an expression are given below. 32 divided by 2 (2 cubed minus 4) Step 1: Equals 32 divided by 2 (8 minus 4) Step 2: Equals 32 divided by 2 (4) Step 3: Equals 32 divided by 8 Step 4: Equals 4 What, if any, was Miguel’s mistake? Miguel made no mistakes. Miguel incorrectly evaluated 2³ in step 1. Miguel incorrectly multiplied before dividing in step 3. Miguel should have used the distributive property in step 1.

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.
