515
624
716

A = event that the NBA Finals was decided in five games

B = event that the NBA Finals was decided in at most five games

C = event that the NBA Finals was decided in at least five games

02

Part (a) Step 2.  In words, the event (B & C) and the number of outcomes that make up the event.

(B & C) refers to the NBA finals, which were determined in five games.

Number of outcome.

(B&C)=15

03

Part (b) Step 1. Given information.

From 1950 through 2012, the number of NBA finals series decided in four, five, six, or seven games is listed in the table below:

GamesFrequency

A = event that the NBA Finals was decided in five games

B = event that the NBA Finals was decided in at most five games

C = event that the NBA Finals was decided in at least five games

04

Part (b) Step 2.  In words, the event (B & C) and the number of outcomes that make up the event.

The NBA Finals were decided in four, five, six, or seven games (B OR C).

Number of outcome

(BorC)=8+15+24+16(BorC)=63

05

Part (c) Step 1. Given information.

From 1950 through 2012, the number of NBA finals series decided in four, five, six, or seven games is listed in the table below:

GamesFrequency
48
515
624
716

A = event that the NBA Finals was decided in five games

B = event that the NBA Finals was decided in at most five games

C = event that the NBA Finals was decided in at least five games

06

Part (c) Step 2.  In words, the event (not A) and the number of outcomes that make up the event.

The NBA Finals were determined in four, six, or seven games (not A).

Number of outcome

(notA)=8+24+16(notA)=48

A = event exactly two heads are tossed,

B = event the first two tosses are tails,

C = event the first toss is heads,
