Answer:
0.8
Step-by-step explanation:
We can solve P(A or B) by using the following:
Since we know P(A) = 0.6, P(B) = 0.3 and P(A and B) = 0.1 we obtain:

First we pick the equation. Let's say we pick first one. From it we express y.
Then we use this y and plug it in instead of y in the second equation.
Now just solve for x.
We plug this x in the first equation.
And solve for y.
So the solution to the equation is geometrically a point P which lies on the intersection of the two lines.

For this case we have the following expression:
We must rewrite both sides of the equation.
For this, we use the distributive property.
We have then:
Adding similar terms we have:
We observe that we have two equal equations.
Therefore, the equations intersect for any value of x.
Thus, the equation has infinite solutions.
Answer:
infinitely many
