Question

If a card is picked at random from a standard 52-card deck, what is the probability of getting a black card or a 3? Give your answer as a fraction.

Answer 1

we know that

Total cards=52

Black cards=26

Number 3 cards=4 ( is included 2 cards black)

so

The probability is equal to

P=(26+4-2)/52

P=28/52

simplify

P=7/13
