MODULE CONDITIONAL PROBABILITY AND INDEPENDENCE



Step 1 of 1



The first three questions refer to the following information:

Suppose a basketball team had a season of games with the following characteristics:


• 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.


Question 1 of 5 Points: 0 out of 10


Of the at-home games, we are interested in finding what proportion were wins. In order to figure this out, we need to find:



P(H)

P(W)

P(H and W)

P(H | W)

P(W | H)

Incorrect




Question 2 of 5 Points: 0 out of 10


Again here is the information about the characteristics of a basketball team's season:


• 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.


Of the at-home games, what proportion of games were wins? (Note: Some answers are rounded to two decimal places.)
