Let first group of people take x candies each

and second group of people take y candies each

5x + 7y will be total candies

5x +7y = 239 (needed to find positive solution of x,y)

now take x=38, y =7

or x=31, y= 12

hence lots of possibilities ,so we can not say exactly

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

The height of a cone is twice the radius of its base. What expression represents the volume of the cone, in cubic units?

Naddika [18.5K]

Answer:

Step-by-step explanation:

Radius = r units

Height = 2r

Volume of cone = (1/3)πr²h

$=\frac{1}{3}*\pi*r^{2}*(2r)\\\\=\frac{2}{3}\pi r^{3}$
