Determine whether $F\left(x\right)=5{x}^{4}-\pi \text{}{x}^{3}+\frac{1}{2}$ is a polynomial.

If it is, state its degree. If not, say why it is not a polynomial. If it is a polynomial, write it in standard form. Identify the leading term and the constant term.

In how many ways can 8 people be seated in a row if a.) there are no restrictions on the seating arrangement(answer is $8!=40,320$ ) , b.) persons A and B must sit next to each other? (Answer: 10,080) , c.) there are 4 men and 4 women and no 2 men or 2 women can sit next to each other? (Answer: 1,152) , d.) there are 5 men and they must sit next to one another? (Answer: 2,880) , e.) there are 4 married couples and each couple must sit together? (Answer: 384). I need to see the steps to solve questions 10b to 10e. I quickly looked through the corresponding chapter on combinatorial analysis and I went over topics such as the multinomial theorem, the basic principle of counting, the binomial theorem, and representing the number of possible combinations of n objects taken r at a time as "n choose r" .

An oil company purchased an option on land in Alaska. Preliminary geologic studies assigned the following prior probabilities.

$PP(\text{high-quality oil})=.50P(\text{medium-quality oil})=.20P(\text{no oil})=.30$

a. What is the probability of finding oil?

b. After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test follow.

$P(\text{soil | high-quality oil})=.20P(\text{soil | medium-quality oil})=.80P(\text{soil | no oil})=.20$

How should the firm interpret the soil test? What are the revised probabilities, and what is the new probability of finding oil?
