Answer:

(a)0.34

(b)0.5

(c)0.185

(d)0.544

(e)0.655

(f)Not disjoint events

(g)Independent events

Step-by-step explanation:

The summary of education levels among party lines is given in the table below

$\left|\begin{array}{c|ccc}&$Democrat &$Republican &$Total\\--&--&--&--\\$College Degree &37 &31 &68\\$No College Degree& 63 &69 &132\\--&--&--&--\\$Total &100 &100& 200\end{array}\right|$

(a)Probability a randomly selected participant has a college degree.

The probability a randomly selected participant has a college degree is:

$=\dfrac{68}{200} =0.34$

(b)The probability that a randomly selected participant is a democrat.

$=\dfrac{100}{200} =0.5$

(c)The probability that a randomly selected participant is a democrat and has a college degree.

$=\dfrac{37}{200} =0.185$

(d)Probability of being a democrat given that the participant has a college degree.

$=\dfrac{37}{68} \approx 0.544$

(e)The probability of begin a democrat or having a college degree

Number of Democrats =100

Number of Those with College degrees = 68

Number of democrats with College degrees =37

Therefore:

Probability of begin a democrat or having a college degree

$=\dfrac{100+68-37}{200} \\=\dfrac{131}{200}\\\\=0.655$

(f)The event of having a college degree and being a democrat are not disjoint events as there are some democrats who have a college degree.

(g)The event of having a college degree and being a democrat are independent events as the outcome of one does not affect the other.

I hope you already know how to find the volume of the prism and cylinder. It is just base x height.

Anyway F and G is correct.
So the volume of the prism: 576
The volume of the cylinder: 942

That means the prism takes 576/942 of the cylinder which is roughly 61%, not 75% as stated by H.

Therefore the answer is H.
