Answer:
I would select the Red color for making money.
Step-by-step explanation:
This is because,
Total no. of brushes= 30+25+25+20= 100
No. of Red brushes= 30
Probability of getting a red brush= 30/100= 0.3
And as the no. of brushes of other colors are less than that of red, we can say that the probability of getting each of those will also be less than that of red ones.
Thus, selecting red color will be profitable.
