Step-by-step explanation:
Probabilities are used to represent the possibilities of events.
The probability that a student participates in a club given that he participates in sports is 0.6561
The required probability is represented as; P(Club | Sport)
And it is calculated using:
![P(Club | Sport) = \frac{n(Club\ n\ Sport)}{n(Sport)}](https://tex.z-dn.net/?f=P%28Club%20%7C%20Sport%29%20%3D%20%5Cfrac%7Bn%28Club%5C%20n%5C%20Sport%29%7D%7Bn%28Sport%29%7D)
From the table, we have:
![n(Club\ n\ Sport) = 620](https://tex.z-dn.net/?f=n%28Club%5C%20n%5C%20Sport%29%20%3D%20620)
![n(Sport) = 945](https://tex.z-dn.net/?f=n%28Sport%29%20%3D%20945)
So, the equation becomes
![P(Club | Sport) = \frac{620}{945}](https://tex.z-dn.net/?f=P%28Club%20%7C%20Sport%29%20%3D%20%5Cfrac%7B620%7D%7B945%7D)
![P(Club | Sport) = 0.6561](https://tex.z-dn.net/?f=P%28Club%20%7C%20Sport%29%20%3D%200.6561)
Hence, (d) 06561 is correct.

Answer:
(f*g)(x) = 3x³+12x²-7x-28
Step-by-step explanation:
What (f*g)(x) means is that we multiply f(x) by g(x):
f(x) = x+4
g(x) = 3x²-7
(f*g)(x) = f(x)*g(x) = (x+4)(3x²-7) = (x)(3x²)+(x)(-7)+(4)(3x²)+(4)(-7) = 3x³-7x+12x²-28 = 3x³+12x²-7x-28
