Answer:
1) The tournament can be played in 10 different ways
2) The probability of 5 games being played is 0.40
3) The probability of a team winning two games in a row is 0.80
Step-by-step explanation:
a) From the tree diagram below we can observe that the tournament can be played in 10 different ways.
b)The probability of 5 games being played is
P= (number of possibilities where 5 games are being played) / (Total games)
P = 4 / 10
P= 0.40
c) The probability of a team winning two games in a row is
P = (number of possibilities where a team wins two games in a row) / Total games
P = 8 / 10
P = 0.80
