Suppose that a bag contains 43 red balls, 54 blue balls, and 72 green balls and that 2 balls are chosen at random without replacement. Construct a probability tree for this problem. What is the probability that 2 green balls will be chosen?

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)
