From a well-shuffled deck of 52 cards, one card is drawn at random. What is the probability that the drawn card is a black 6?
Total number cards in a deck = 52
Chances of drawing a black 6 from the deck of cards = 2 (they are 8 of clubs and 8 of spades)
Probability P() = 
Probability of drawing a black 6 from a deck of cards P(black 6)
