Quizplus · Accepted Answer

There are four sevens of each suit, making a total of 4x4=16 sevens in the deck. There are 26 black cards (13 spades and 13 clubs) in the deck. So the total number of cards that are either sevens or black is 16+26=42. Therefore, the probability of drawing either a seven or a black card is 42/52=21/26=7/13.
