Answer:

Pr = \frac{1}{2002}

Step-by-step explanation:

See comment for complete question;

Given

n = 14

r = 5 -- committee members

k = 4 ---- officers (i.e. president, CEO, COO and CFO)

Required

Probability of selecting 5 youngest qualified members

First, we calculate the number of ways the committee can be appointed;

Any 5 members can be part of the committee; This means that we won't consider the order.

So, the number of ways is:

^{14}C_5

This gives:

^{14}C_5 = \frac{14!}{9!5!}

So, we have:

^{14}C_5 = \frac{14*13*12*11*10*9!}{9!*5*4*3*2*1}

^{14}C_5 = \frac{14*13*12*11*10}{5*4*3*2*1}

^{14}C_5 = \frac{240240}{120}

^{14}C_5 = 2002

There can only be a set of 5 young people. So, the probability is:

Pr = \frac{1}{2002}

(d):  y = mx+n

m = -2/3 ⇒ y = (-2/3)x +n

A(-4,  6) ∈ d  ⇒ 6 = (-2/3)·(-4) +n ⇒ 6 = 8/3 +n ⇒

⇒ n = 6 - 8/3 ⇒ n = 10/3

Now, we have:

y = (-2/3)x +10/3
