Step-by-step explanation:
i got it right
What you want to do is add the probabilities up and divide by how many there are so it will be 0.4+1.8+0.2-0.8/4
Which is 0.35

First of all, expand the left hand side:

Sum like terms:

Add 3 to both sides:

Subtract 3x from both sides:

So this is the solution. Every number smaller than 8 (excluded) is part of the solution of this inequality.
