Answer:

4% probability that he will correctly predict the two teams to play in the championship just by guessing

Step-by-step explanation:

A probability is the number of desired outcomes, divided by the number of total outcomes.

League A:

5 teams, he will predict one to be champion. So

[tex]P(A) = \frac{1}{5}[/tex]

League B:

5 teams, he will predict one to be champion. So

[tex]P(B) = \frac{1}{5}[/tex]

What is the probability that he will correctly predict the two teams to play in the championship just by guessing

[tex]P(A \cap B) = P(A)*P(B) = \frac{1}{5}*\frac{1}{5} = \frac{1}{25} = 0.04[/tex]

4% probability that he will correctly predict the two teams to play in the championship just by guessing
