Using permutations and the probability concept, it is found that there is a 0.0417 = 4.17% probability that Nia is chosen as president.

A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.

As there are different roles, the order in which the students are chosen is important, hence, the <em>permutation </em>formula is used to solve this question.

Permutation formula:

The number of possible permutations of x elements from a set of n elements is given by:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

Desired outcomes:

Nia's president.

For the other roles, 3 students from a set of 23, hence:

$D = P_{23,3} = \frac{23!}{20!} = 10626$

Total outcomes:

4 students from a set of 24, hence:

$T = P_{24,4} = \frac{24!}{20!} = 255024$

Then:

$p = \frac{D}{T} = \frac{10626}{255024} = 0.0417$

0.0417 = 4.17% probability that Nia is chosen as president.

Find the area of an equilateral triangle (regular 3-gon) with the given measurement.

kow [346]

If the perimeter is 9 inches, each side is 3 inches.

The height of an equilateral triangle splits the triangle in two right sub-triangles: for example, consider a triangle ABC and the height AH starting from A, perpendicular to BC.

The triangle AHC is a right triangle, whose legs are AH and HC, and whose hypotenuse is AC.

AH is half the side, and AC is a side. So, we can use the Pythagorean theorem to find the height:

$AH = \sqrt{AC^2-AH^2}=\sqrt{l^2-\dfrac{l^2}{4}}=\dfrac{\sqrt{3}l}{2}$

So, the area is

$\dfrac{AH\cdot HC}{2} = \dfrac{l\cdot\frac{\sqrt{3}l}{2}}{2} = \dfrac{l^2\sqrt{3}}{4} = \dfrac{9\sqrt{3}}{4}$
