There are 13 hearts in a deck of 52 cards. So the probability of drawing a heart is 13/52 or 1/4. To find out what the chances of all three being hearts, we can multiply this probability:

\sf\dfrac{13}{52}\times\dfrac{12}{51}\times\dfrac{11}{50}\rightarrow\boxed{\sf\dfrac{11}{850}}

So the chances that all three cards will be hearts is 11/850.

Total number of cards = 52
Total number of hears = 13

Assuming the cards drawn are not replaced:
P(3 hearts) = (13/52)(12/51)(11/50) = 11/850

Answer: 11/850

fredd [130]

Answer:

Step-by-step explanation:

5x + 7x - 1/2x + 1/4 = 6

move x to one side move numbers to the other side

5x + 7x - 1/2 x = 6 - 1/4

add x and numbers

23/2x = 23/4

divide both side by 23/2

x = (23/4)/(23/2)

  = 1/2

plug it in to check the answer

5/2 + 7/2 - 1/4 + 1/4 = 6

12/2 = 6

The sum of three consecutive integers is 90. Find the three numbers by letting x
Law Incorporation [45]

Answer:

x = 28

Step-by-step explanation:

let us take three consecutive numbers be (x + 1), (x + 2) and (x + 3)

Now,

The sum of three consecutive integers is 90

i.e.,

(x + 1) + (x + 2) + (x + 3) = 90

x + 1 + x + 2 x + 3 = 90

3x + 6 = 90

3x = 90 - 6

3x = 84

x = 84/3

x = 28

x = 28Thus, The value of x is 28

<h2><em><u>VERIFICATION</u></em><em><u>:</u></em></h2>

(x + 1) + (x + 2) + (x + 3) = 90

(28 + 1) + (28 + 2) + (28 + 3) = 90

28 + 1 + 28 + 2 + 28 + 3 = 90

90 = 90
