Answer:
a²+2a-8
Step-by-step explanation:
You have to consider the sample space. In this example the sample space
is {1,2,3,4,5,6}
A simple event can be defined as a SINGLE outcome : Example getting a 3 OR 5 OR any other number from the sample space.
Now if you roll 1 dice & you want to get an even number (2,4,6) then you have chosen from the sample space 3 outcome & this is a compound event
Equally if you roll 2 dice and want to get "one" and/or "three" this is a compound event since you have chosen 2 outcome from the sample space.
Mind you, if you want 5 And 5 when rolling two dice it's a simple event because you have chosen ONE outcome from the sample space.
Hope this will help you to understand this kind of problem
A is 5 , b is 1 , c is 4 , d is 3, and E is 2

Step-by-step explanation:
Formula = Gross profit / Cost of item * 100 First we find the Cost of item = 39.99 / 06 = 66.65 as 66.65 * 0.60 = 39.99 then we find the Gross profit 66.65 - 29.99 = 36.66 then plug into the formula 36.66/66.65 * 100 =55.0037509% = 55%
