Answer:
Given that your friend in not really psychic, he has a probability of P=1.5% of guessing right 15 out of 20 coin flips.
Step-by-step explanation:
We have a binomial distribution problem.
We have to calculate the probability of correctly guessing 15 out of 20 flips of a coin (probability of success for every trial: p=0.5).
