Answer: 2/13
Step-by-step explanation:
In a standard deck of 52 cards, there are 4 sevens and 4 kings, making a total of 8 cards that are either a 7 or a king. The probability of drawing one of these cards is the number of favorable outcomes divided by the total number of possible outcomes. Therefore, the probability is
8/52
. Simplifying this fraction by dividing both the numerator and the denominator by their greatest common divisor, 4, gives
2/13
. Hence, the probability of selecting a 7 or a king from a standard deck is
2/13
