Question

Give an expression for the answer using permutation notation, combination notation, factorial notation, or other operations. Then evaluate. Of the first 10 questions on a test, a student must answer 6. Of the second 5 questions, the student must answer 4. In how many ways can this be done? Identify which notation properly depicts the solution to this problem. Select all that apply. A. $10P_4$ C. $frac{10!}{6!(10-6)!} cdot frac{5!}{4!(5-4)!}$ E. $frac{10!}{4!(10-4)!}$ G. $10C_4$ I. $10P_6 cdot 5P_4$ K. $frac{10!}{6!(10-6)!} + frac{5!}{4!(5-4)!}$ There is a total of ways to do this test. (Simplify your answer.) B. $frac{10!}{(10-4)!}$ D. $10P_6 + 5P_4$ F. $10C_6 cdot 5C_4$ H. $frac{10!}{(10-6)!} + frac{5!}{(5-4)!}$ J. $frac{10!}{(10-6)!} cdot frac{5!}{(5-4)!}$ L. $10C_6 + 5C_4$
