From a pack of 52 cards, one card is drawn at random. What is the probability that the card drawn is a ten or a spade?

$\frac{4}{13}$

Number of cards of 10 number = 4

Total number of spade card including 10 = 13

Number of desired card = 13 + 4 - 1 = 16

Total number of cards = 52

Probability that the card drawn is a ten or a spade = \(\frac{16}{52}\)

= \(\frac{4}{13}\)
