**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 )

=

=

**Answer:**

there's really no real answer it would take a few day to a weak or more it depends on a variety of factors

**Answer:**

If both computers are working together, it will take 24 minutes to do the job

**Step-by-step explanation:**

It is given that,

There are two computers.The slower computer can send all the company's email in 60 minutes.

The faster computer can complete the same job in 40 minutes

<u>To find the LCM of 40 and 60</u>

LCM (40, 60) = 120

<u>To find efficiency of 2 computers</u>

Let x be the efficiency of faster computer and y be the efficiency of faster computer

x = 120/40 = 3

y = 120/60 = 2

then, x + y = 3 + 2 = 5

Therefore efficiency of both the computer work together = x + y =5

<u>To find the time taken to work both the computer together</u>

time = 120/5 = 24 minutes

No her answers are not correct. If you multiply a negative number an even amount of times, the product will be positive
