Accepted Solution

A:

Answer:1) The tournament can be played in 10 different ways 2) The probability of 5 games being played is 0.403) 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 / 10P= 0.40c) The probability of a team winning two games in a row isP = (number of possibilities where a team wins two games in a row) / Total gamesP = 8 / 10P = 0.80
