Question

If one card is drawn from a standard deck of 52 playing cards, what is the probability of drawing a number card (Ace, 2-10)?

Answer 1

Total number of events = Total number of cards = 52

Number of favorable events = Number of number cards :

Number of Ace cards = 4

Number of 2 cards = 4

Number of 3 cards = 4

Number of 4 cards = 4

Number of 5 cards = 4

Number of 6 cards = 4

Number of 7 cards = 4

Number of 8 cards = 4

Number of 9 cards = 4

Number of 10 cards = 4

So,

Number of favorable events = Number of number cards := 10 X 4 = 40

So,

the probability of drawing a number card (Ace, 2-10) =40/52 = 0.7692

So,

Answer is:

0.7692
