Context A: Jenny needs to determine the number of three letter arrangements of the letters of the word MATH. Context B: Ross needs to find the number of 4-person committees that can be formed from a class of 20 people. Context C: Rob needs to determine the number of arrangements of four books as part of a display shelf. Context D: Deanna needs to determine the number of three digit security codes that can be formed from the digits 0 through 9 where digits cannot be repeated. 13. For each context, use 1 to indicate that it should be solved using a permutation, and use 2 to indicate that it should be solved using a combination. Context A should be solved using a Context B should be solved using a Context C should be solved using a Context D should be solved using a Use the following information to answer question 14.
