6) A standard deck has 52 cards, and contains 13 cards of each of the four suits: diamonds, spades, hearts, and clubs. What is t
Crazy boy [7]

Answer:

\dfrac{12}{51}\cong\dfrac{4}{17}

Step-by-step explanation:

You have 52 cards in a deck and 13 cards of each suit.

The probability of picking a diamond in a complete deck of cards is:

\dfrac {13}{52}

Or the probability is 13 put of 52.

Since you took out 1 diamond card already there would be only 51 cards left and 12 diamond cards left. So you would have a probability of:

\dfrac{12}{51}

If we simplify it you will have a probability of:

\dfrac{4}{17}

Write 12 1/3 as an improper fraction.
Julli [10]

Answer:

\frac{37}{3}

Step-by-step explanation:

12\frac{1}{3}

When converting mixed numbers (such as the one above), to improper fractions, we must first multiply the whole number by the denominator:

12*3=36

Then, add the numerator the the product:

36+1=37

Now, put the sum over the denominator to get your solution:

\frac{37}{3}

-

To check your work, you can convert the improper fraction to a mixed number to make sure you will end up with 12\frac{1}{3}.

Divide 37 into 3:

12 with a remainder of 1

Put the remainder over the denominator:

12\frac{1}{3}

Therefore, our solution is correct!
