Answer:

See Annex for tree diagram and all probabilities

b) P(2y) = 0,329

Step-by-step explanation:

a) Attached

b) Probability of the second ball is yellow P(2y) is equal to the probability of the second ball is yellow given that the first one is black ( 0,204 ) plus the probability f the second ball is yellow given that the first one is yellow ( 0,125)

P(2y) = 0,204 + 0,125

P(2y) = 0,329

A is the correct answer because when using the distributive property it is the only example that results in x^2-x-20.

(x+4)(x-5)

x*x=x^2, x*-5=-5x, 4*x=4x, 4*-5=-20. Now combine all alike terms for your final answer. x^2-x-20..
