A poker hand consisting of 7 cards is dealt from a standard deck of 52 cards. Find the probability that the hand contains exactl

77julia77 [94]

Answer:

The probability is 2,010,580/13,378,456

Step-by-step explanation:

Here is a combination problem.

We want to 7 cards from a total of 52.

The number of ways to do this is 52C7 ways.

Also, we know there are 12 face cards in a standard deck of cards.

So we are selecting 3 face cards from this total of 12.

So also the number of cards which are not face cards are 52-12 = 40 cards

Out of all these 40, we shall be selecting exactly 4. The number of ways to do this 40C4

Thus, the required probability will be;

(40C4 * 12C3)/52C7 = (91,390 * 220)/133,784,560

= 20,105,800/133,784,560 = 2,010,580/13,378,456

I need some help please!<br> K is the midpoint or segment JL. JL=3x-15 <br> JK=18<br> Find x.

vazorg [7]

Because K is the midpoint of JL and JK = 18, KL must also equal 18. So the equation would be 3x - 15 = 36 because you add 18 + 18. You then add 15 to both sides to get 3x = 51. Then you divide by 3 on both sides to get x = 17.

$4000 principal earning 6% compounded annually after 5 years

sergij07 [2.7K]

If $4000 is the principal, compounded annually at 6%per annum for five years, then-
Amount=principal *(1+rate/100)^5
=4000*(1+6/100)^5
=4000*(53/100)^5
=5352.90
Therefore, Compound Interest =5352.90-4000
=$1352.90
Please recheck the calculation.
