A company that has 250 employees chooses a committee of 12 to represent employee retirement issues. When the committee is formed, none of the 56 minority employees are selected. (a) Use technology to find the number of ways 12 employees can be chosen from 250. (b) Use technology to find the number of ways 12 employees can be chosen from 194 nonminorities. (c) What is the probability that the committee contains no minorities when the committee is chosen randomly (without bias)? (d) Does your answer to (c) indicate that the committee selection is biased? Explain your reasoning. (a) There are ways to choose 12 employees from 250 employees. (Use scientific notation.
