A Correct answer
Explanation

A standard deck has 26 red cards and 26 black cards. The probability of drawing either is (26+26)/52 = 52/52 = 1.

AI explanation

A standard pack of playing cards is divided entirely into red cards and black cards, which are mutually exclusive and exhaustive events. Drawing a single card guarantees it will fall into one of these two categories. Therefore, the probability of drawing either a red card or a black card is 1.
