What is the probability of drawing 2 cards in succession (without replacement) from a standard deck and having them both be face
Lesechka [4]

Answer:      \dfrac{11}{221}

Step-by-step explanation:

We know that the total number of cards in a standard deck = 52

Then the number of ways to draw any two card = 52 x (52-1)

= 52 x 51 = 2652   [By Multiplicative principle]

Also , there are 12 face cards in a standard deck , so the number of ways to draw two face cards in succession = 12 x (12-1)

12 x 11= 132   [By Multiplicative principle]

Then, the probability of drawing 2 cards in succession (without replacement) from a standard deck and having them both be face cards would be

\dfrac{\text{ Number of ways to draw 2 face cards}}{\text{Total number of ways to draw two cards}}

=\dfrac{132}{2652}=\dfrac{11}{221}

Hence, the required probability is  \dfrac{11}{221} .

masha68 [24]

Answer:

Option (C)

Step-by-step explanation:

An 8 pound box of halibut steaks is ordered costing $4.50 per pound. If each steak weighs 4 ounces, what is the cost of each ste
luda_lava [24]
8 pounds * 16 ounces/pound * 1 steak/4 ounces = 32 steaks
8 * 16 * 1/4 = 32

8 pounds * $4.50/pound = $36.00
8 * 4.5 = 36

$ / steak:
$36.00 / 32 steaks = $1.125/steak

That's a really good deal ;)

coldgirl [10]

Answer:
