Permutation combination question. Need answer in a different approach?
Question: Jack buys 5 dolls for his 5 nieces. The 5 dolls are 2 identical beach dolls, 1 barbie, 1 GI Joe, 1 Tulip troll doll.If the youngest niece does not want GI Joe doll, how many different ways can he give the gifts ?
Answer: Total number of ways in which 5 dolls can be given to his 5 nieces = 5!/2!
Total number ways in which he can give 5 dolls with GI Joe going to the youngest niece = 4!/2!
Final answer, total number of ways Jack can give dolls, with the youngest niece NOT getting GI Joe is = 5!/2! - 4!/2! = 48
Method 2:
# of ways dolls can be given to youngest niece (Niece5) without she getting GI Joe *
# of ways dolls can be given to Niece1 *
# of ways dolls can be given to Niece2 *
# of ways dolls can be given to Niece3 *
# of ways dolls can be given to Niece3 = 3 * 4!/2! * 3!/2! * 2!/2! * 1 = 108
How come I 'm not getting the answer by method 2 ? Where is it fundamentally wrong ?
method 2 corrected
----------------------------
consider youngest nice as one block & the rest together as another block
two cases
(a) youngest gets beach doll: 1 way for youngest * 4! ways for rest = 24
(b) youngest gets barbie or troll doll: 2 ways for youngest * 4!/2! for rest = 24
so total permissible ways = 48
