Answer:
The probability that he teleports at least once a day =  
Step-by-step explanation:
Given - 
Evan lives in Stormwind City and works as an engineer in the city of ironforge in the morning he has three Transportation options teleport ride a dragon or walk to work and in the evening he has the same three choices for his trip home.
Total no of outcomes = 3
P( He not choose teleport in the morning ) = 
P( He not choose teleport in the evening ) = 
P ( he choose teleports at least once a day ) = 1 - P ( he not  choose teleports in a day )
                                                          = 1 - P( He not choose teleport in the morning )  P( He not choose teleport in the evening )
 P( He not choose teleport in the evening )
                                           =  
                                            =
