5.3% is the probability of an expensive painting, since this is calculated by dividing the total number of paintings by the number of paintings you will carry, this is the definition of probability.

Not really, Hint: when he picks the first painting, he has 5/94 chance to get a expensive one. What about pick 2?

A thief is in a house to steal paintings but finds 94 different ones. He knows that there is 5 expensive paintings and he can only carry 5 paintings. Can you calculate for the thief, what are the odds of him stealing 1 expensive painting? Look, it's just a painting.
