Answer:
Guessing 8 games correctly is an unusual outcomes, significantly better than just guessing, which means tht Paul has psychic powers
Step-by-step explanation:
For each game, there are only two possible outcomes. Either Paul guesses the winner correctly, or he does not. The probability of guessing the winner of a game is independent of other games. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

The standard deviation of the binomial distribution is:

Outcomes that are more than 2.5 standard deviations from the mean are considered unusual.
Paul guesses one team out of two.
So 
Eight games
So 
1 Does Paul have psychic powers? In other words, is an 8 for 8 record significantly better than just guessing?
Let's find if 8 is an unusual outcomes.


Guessing 6 or more games correctly are unusual outcomes.
Guessing 8 games correctly is an unusual outcomes, significantly better than just guessing, which means tht Paul has psychic powers
