A deck of 108 cards contains an equal number of each color: red, yellow, green, and black. If a card is chosen at random, what is the probability that it is black? The answer must be a fraction.

Answer 1

Since there are equal numbers of each color in the deck, the probability of choosing a black card is the number of black cards divided by the total number of cards in the deck.

There are 27 black cards in the deck (since there are 108 cards total and 1/4 of them are black).

Therefore, the probability of choosing a black card is:

27 (number of black cards) / 108 (total number of cards) = 27/108 = 1/4

So, the probability of choosing a black card from the deck is 1/4.
