The easy way
RED GREEN WHITE BLUE
?------1/3--------1/4------?

OK. NOW MAKE A SUM
1/3 + 1/4 …. = 7/12
This is the combined probability of green and white.

Now only make a sustracction from the 100% or total that is 12/12, or simply 1

1- 7/12 = 5/12
That is the probability of blue and red combined.

i think the result is 20 and not 1.8.
9x= 10(x-2)
9x = 10x -20
x=20
ok the result is 20

but remember this
And the result have to be replaced in whatever equation that you want.
so
(10x "20")- 20
= 180 cents

R=9X 9 bottles multiplicated X cents
R=10(X-2) 10 bottles multiplicated X cents MINUS 2 cents.

Now simply mathematic.
9x=10(x-2)
Bla……
And the result have to be replaced in whatever equation that you want.
Bla….
The result
1.8
