Six marbles are contained in each of Ariana's two pots. Ariana selects a pot at random, pulls a marble at random, then removes another marble at random from the same pot without returning the first marble.

Pot 1 contains: 4 black marbles, and 2 white marbles.

pot 2 contains: 1 black marble and 5 white marbles.

a) Draw the probability tree for pot, marble 1, and marble 2. ( PLEASE DRAW GOOD)

b) What is the probability that a black marble is drawn, then a white marble (in that order)?

c) What is the probability that both marbles drawn are white?

d) If both marbles selected are white, what is the probability Ariana was drawing from the first pot? Explain
