  • 60% of all the games were at-home games. Denote this by H (the remaining were away games).
  • 25% of all games were wins. Denote this by W (the remaining were losses).
  • 20% of all games were at-home wins.

If the team won a game, how likely is it that this was a home game? (Note: Some answers are rounded to 2 decimal places.)

   .05

   .12

   .15

   .33

   .80

Let A and B be two independent events. If P(A) = .5, what can you say about P(A | B)?

   Cannot find it since P(B) is not known.

   Cannot find it since P(A and B) is not known.

   Cannot find it since both P(B) and P(A and B) are not known.

   It is equal to .5.

   It is equal to .25.
