26/52

The probability of drawing a red or black card from a standard deck of playing cards is 1 (a certainty). This is because these are the only options available.

There are 52 cards of which 26 (a half) are black. So he probability that the first card is black is 26/52= 1/2

Excluding jokers, the probability is 1 in 2.

Half the cards in a standard pack are black. Therefore the probability of drawing a black card is 1/2. Half the sides of a coin are "heads" so again the probability is 1/2. Therefore the probability you will both draw a black card and flip heads = 1/2 * 1/2 = 1/4.
