Evaluate the given binomial coefficient. $$\left(\begin{array}{l}8 \\\3\end{array}\right)$$

$$\begin{array}{|l|c|c|c|c|} \hline & \text { Married } & \text { Never } & \text { Divorced } & \text { Widowed } & \text { Total } \\ \hline \text { Male } & 65 & 40 & 10 & 3 & 118 \\ \hline \text { Female } & 65 & 34 & 14 & 11 & 124 \\ \hline \text { Total } & 130 & 74 & 24 & 14 & 242 \\ \hline \end{array}$$ If one person is randomly selected from the population described in the table, find the probability, expressed as a simplified fraction and as a decimal to the nearest hundredth, that the person is divorced.

Write the first four terms of each sequence whose general term is given. $$a_{n}=3 n+2$$

Write the first five terms of each geometric sequence. $$a_{1}=5, \quad r=3$$

Write the first six terms of each arithmetic sequence. $$a_{1}=200, d=20$$

Use the formula for \(_{n} P_{r}\) to evaluate each expression. $$_{7} P_{3}$$

Write the first five terms of each geometric sequence. $$a_{1}=4, \quad r=3$$

Write the first four terms of each sequence whose general term is given. $$a_{n}=4 n-1$$

Write the first six terms of each arithmetic sequence. $$a_{1}=300, d=50$$

$$\begin{array}{|l|c|c|c|c|} \hline & \text { Married } & \text { Never } & \text { Divorced } & \text { Widowed } & \text { Total } \\ \hline \text { Male } & 65 & 40 & 10 & 3 & 118 \\ \hline \text { Female } & 65 & 34 & 14 & 11 & 124 \\ \hline \text { Total } & 130 & 74 & 24 & 14 & 242 \\ \hline \end{array}$$ If one person is randomly selected from the population described in the table, find the probability, expressed as a simplified fraction and as a decimal to the nearest hundredth, that the person has never been married.
