Given a standard deck of cards, and you draw a single card at random. what is the probability of drawing
a 7 or an 8?

Probability of drawing  a 7 or an 8  is

Step-by-step explanation:

Total number of cards in the given deck = 52

Now, the number of 7  in the deck = 4

Also, the number of  8 in the deck = 4

So, the total number of ( 7 + 8) in the deck = 4 + 4 = 8 cards

Let E: Event of picking a 7 or an  8

Here, the total number of favorable outcomes =  8

Now,

So, here

or, P(Picking a 7 or 8)  = 2/13

Hence, The probability of drawing  a 7 or an 8  is

answer: 2/4
