Question

Complete the following table of joint probabilities of the 6 joint events that describe the commuting time and the annual salary and wage income of all U.S. fulltime workers in 2010. Use the table of joint probabilities to answer the following questions: Report your answers to 2 decimal places (to the .00 place.) What is P(E)? ___________________ What is P(A and D)? ___________________ What is P(C or E)? ___________________ What is P(B and C)? ___________________ WhatisP(A')? ___________________

Explanation / Answer

(i)P(E)=0.63

(ii)P(AnD)=0.14

(iii)P(C or E)=0.01+0.26+0.15+0.22=0.64

(iv)P(B and C)=0 as no event is common to them

(v) P(A')=1-P(A)=1-0.36=0.64

A B C Total D 0.14 0.22 0.01 0.37 E 0.22 0.15 0.26 0.63 Total 0.36 0.37 0.27 1
