Ajar initially contains 4 red balls. we have two additional balls, both colored green, called g1 and g2, that we might add to the jar. to decide if we add them, we flip a fair coin twice: if the first flip is heads, we add g1 to the jar (and leave g1 out if the flip is tails), and if the second flip is heads, we add g2 to the jar (again, leaving it out if the flip is tails). (a) after flipping the coin twice and adding the green balls to the jar if appropriate, we draw a random ball from the urn. what is the probability that we draw a red ball?
