Problem 2 An urn contains 5 white balls and 7 black balls. Draw a ball and do not put it back into the urn. Then draw a second ball. (1) Define an appropriate probability space (2, 4, P) to describe the experiment. (2) Describe the following events as subsets of the sample space : W₁ := "The first ball is white" B₁ := "The first ball is black" W₂ := "The second ball is white" B₂: "The second ball is black" (3) Compute P(W₂ | W₁), P(W₂ | B₁), and P(W₂). (4) Are W₁ and W₂ independent? Justify your claim mathematically!

From long experience a landlord knows that the probability an apartment in a complex will not be rented is 0.10. There are 20 apartments in the complex, and the rental status of each apartment is independent of the statue of the others.

Round to 4 decimal places. b) What is the probability that four or fewer units are unrented?
