Two cards are drawn from a standard deck of 52 cards. what is the probability of drawing a 9 or a diamond?
(hint: in a standard deck of 52 cards, each card has 4 suits: hearts, diamonds, spades, and clubs.)

7⁄52 = 13.5%

17⁄52 = 32.7%

1⁄4 = 25%

4⁄13 = 30.8%

2⁄13 = 15.4%

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.  

The size of the sample space is the total number of possible outcomes  

The event space is the number of outcomes in the event you are interested in.  

so  

Let

x------> size of the event space

y-----> size of the sample space  

so

step 1

Find the probability of drawing a 9

In this problem we have

substitute

step 2

Find the probability of drawing a diamond

In this problem we have

substitute

step 3

Find the probability of drawing a 9 or a diamond

Adds the the probability of drawing a 9 plus the probability of drawing a diamond

so

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

i think the answer is 90 hope this
