Permutations and Combinations help

  1. Jan 25, 2015 #1
    Having problems with question 9 and what I came up was


    Case 1:
    1st person gets 1 And
    2nd person gets 3

    OR

    Case 2:
    1st person gets 3 And
    2nd person gets 1

    OR

    Case 3
    They both get 2

    And seeing that they are both dependent events so that once a person receives an article it affects the amount the next person gets. I used permutations for each of the two scenarios for each case, multiplied them and added them all together but I don't get the correct answer which is 14. What am I doing wrong???

    Are the articles supposed to be distinguishable? Do you reckon it matters?

    As long as the 4 articles are distinguishable, 14 is correct. Cases 1 and 2 have 4 possibilities each, while case 3 has 6.
