Anarel [89]

Answer:

Step-by-step explanation: u hv 2 make a table for x and y and put in #'s like 1,2,3,4 so u get 1 side of the parabola. x-1, y-11/x-2,y-11/x-3,y-11/x-4,y-14; here u c that u have 2 y's=11 so the points between are the Vertex Points of (2,10)

X has a coefficient, the vertext is (2,10)

An urn contains n balls, one of which one is special. If k of these balls are withdrawn one at a time, with each selection being

Aleksandr [31]

Using it's concept, it is found that the probability that the special ball is chosen is given by:

$p = \frac{1}{C_{n,k}}$

<h3>What is a probability?</h3>

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

The total number of outcomes is given by the combination of k balls from the set of n balls, given by:

$C_{n,k} = \frac{n!}{k!(n - k)!}$

One ball is special, hence the probability the special ball is chosen is given by:

$p = \frac{1}{C_{n,k}}$
