#probability
I have a bag containing 20 red balls and 16 blue balls. I uniformly randomly take balls out from the bag without replacement until all balls of color have been removed. If the probability that the last ball I took was red can be represented as p/q , where p and q ... of drawing all the balls is 36c20. The probability is 35c19/36c20=5/9. but the answer is 4/9. pls, correct my solution?

Consider the following on-line learning method to estimate the expected value of a real-valued random variable X. We begin with an initial estimate µ0, and then for t = 1, 2, . . . , Obtain xt as an independent identical distribution (i.i.d) sample of X ... t. Assume X is normally distributed with mean µ and variance σ 2 . If we choose αt = 1 t , then E[µt ] is
