John claims to be a connoisseur of wine. To test his expertise, he is given 8 cards with the names of 8 types of
red wine. He is then presented 8 glasses of these wines and, after tasting them, he has to put one card at each glass.
To be acknowledged as a connoisseur of wine, he should guess at least 5 names correctly.
Suppose John is not an expert on wines at all.
What is the probability that he will be acknowledged as a connoisseur of wine?
