ANSWER:

The answer is 30.77%

STEP-BY-STEP EXPLANATION:

The probability would be the number of cards that meet the conditions divided by the total number of cards.

The pack of cards is a “Standard Pack", that is it has 4 suits (Diamonds, Hearts, Spades, Clubs), and cards Ace, 2 to 10 inclusive in each suit and Jack, Queen and King in each suit, giving a total of 52 cards.

There are 3 Face Cards in each suit (Jack, Queen, King)

Therefore there are 3 Face Cards in each suit in the pack or 3 x 4 (or 12) Face Cards in the pack.

Card 2, there is 4 times one for 4 suit.

Therefore:

$P(\text{face, 2})=\frac{12+4}{52}=\frac{16}{52}=0.3077=30.77\text{\%}$

8x-12=36

Let's solve your equation step-by-step.

8x−12=36

Step 1: Add 12 to both sides.

8x−12+12=36+12

8x=48

Step 2: Divide both sides by 8.

8x/8=48/8

x=6

Answer: x=6

How do you solve 2/3 [(5+3) ^-3]

vodka [1.7K]

$\dfrac{2}{3}[(5+3)^{-3}]=\dfrac{2}{3}(8)^{-3}\\\\\text{use}\ a^{-n}=\dfrac{1}{a^n}\\\\=\dfrac{2}{3}\cdot\dfrac{1}{8^3}=\dfrac{2}{3\cdot512}=\dfrac{1}{3\cdot256}=\dfrac{1}{768}$
