A single card is chosen at random from a deck of 52 cards, the probability that a face card (jack , queen, king) is selected is . Does this probability mean that, if you choose a card at random 13 times, a face card will appear 3 times? If not, what does it mean?
 Yes. No, it means that if a card was chosen at random from a deck of 52 cards many times, about  of the outcomes would be face cards. No, it means that if a card was chosen at random from a deck of 52 cards exactly 52 times, exactly 12 outcomes would be face cards. No, a probability of   tells us nothing.

The probability of rolling an even number on a die is . If you roll the die two times, does this probability mean that one even number will appear? If not, what does it mean?
 Yes. No. A probability of  tells us nothing. No. It means that if a die were rolled many times, about  of the outcomes would be even numbers. No. But if the die were rolled 10 times, 5 outcomes would be even numbers.
