What is the i^2 ? i will mark as

Step-by-step explanation:

By definition, is known as "Imaginary unit" (It is also called "Unit imaginary number") and this is:

 In this case you need to find , so you need to remember the following property:

Therefore, in order to find , you must square both sides of the equation :

FInally. you must apply the property shown before. Through this procedure you get that the value of is the shown below:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
