Question

A card is drawn from a well-shuffled deck of 52 cards. Find the probability that the card is a black card or a 8.
The probability is
(Type an integer or a simplified fraction.)

Answer 1

Answer:

7/13

Step-by-step explanation:

There are a total of 13 spades and 13 clubs for a total of 26 black cards.

There are also four 8's, but two of them are black.

Pblack= 26/ 52

P8 = 4/52- 2/52= 2/52

Now you would add the two probabilities:

P= 26/52 + 2/52= 28/52= 7/13
