1 answer:

5 0

(7x^2 - 10x - 10) - (2x + 4)^2

(7x^2 - 10x - 10) - (4x^2 + 8x + 8x + 16)

(7x^2 - 10x - 10) - (4x^2 + 16x + 16)

(7x^2 - 4x^2) + (- 10x - 16x) + (- 10 - 16)

3x^2 - 26x - 26

The grade appeal process at a university requires that a jury be structured by selecting eight individuals randomly from a pool

anygoal [31]

Answer: The probability of selecting a jury of all faculty=0.000071

The probability of selecting a jury of six students and two two faculty=0.3667

Step-by-step explanation:

Given: The number of students = 9

The number of faculty members=11

The total number of ways of selecting jury of eight individuals= $^{20}C_8=\frac{20!}{(20-8)!\times8!}=125970$

The number of ways of selecting jury of all faculty= $^9C_8=\frac{9!}{8!(9-8)!}=9$

The probability of selecting a jury of all faculty= $\frac{9}{125970}=0.000071$

The number of ways of selecting jury of six students and two two faculty

$=^9C_6\times ^{11}C_2=\frac{9!}{6!(9-6)!}\times\frac{11!}{2!\times(11-2)!}\\=84\times55=4620$

Now, the probability of selecting a jury of six students and two two faculty

$=\frac{4620}{125970}=0.03667$
