Answer:
choice b maybe?
Step-by-step explanation:
A simple event is the one which has only one possible outcomes, hence such an event does not involve addition or multiplication of probabilites.
The option B gives only such a probability which can represent a simple event. The rest of the options belong to the compound events as they are sum or product of probabilities.
So, the correct answer is option B
First, you will start with distributive property. on the right side you will distribute 4 into x and 3.
the equation will become:
2x + 22 = 4x + 12
then you have to get x on only one side of the equal sign. subtract 2x from 4x and the equation becomes:
22 = 2x + 12
subtract 12 from 22:
10 = 2x
divide 10 by 2:
5 = x
or
x = 5
