<u>Step-by-step explanation:</u>
(i) The first leaf of the tree is: black = 5/9 and white = 4/9
That means that there are 5 black marbles out of 9 total marbles and 4 white marbles out of 9 total marbles.
Total marbles = 9
Black marbles = 5
White marbles = 4
*******************************************************************************************
(ii)
P(B₂/B₁)
The probability that the 2nd marble is black given that the 1st marble was black.
P(W₂/B₁)
The probability that the 2nd marble is white given that the 1st marble was black.
P(B₂/W₁)
The probability that the 2nd marble is black given that the 1st marble was white.
P(W₂/W₁)
The probability that the 2nd marble is white given that the 1st marble was white.

(iii) <u>Outcomes </u> (iv) <u> Probability </u>
(B, B) (5/9) x (1/2) = 5/18
(B, W) (5/9) x (1/2) = 5/18
(W, B) (4/9) x (5/8) = 5/18
(W, W) <u> (4/9) x (3/8) = </u><u>3/18</u>
Check: Total = 18/18 = 1

(iv) Dependent
Once the first ball is drawn, there is one less ball for the second draw. Therefore, the second draw is dependent on the first draw.
