trileets:
4 0 0 0: 1 wayMay I know how this qn is done?
Find the number of ways to put 4 different coloured marbles into 4 identical empty boxes.
Ans: 15 (my ans of 24 is wrong)
TIA
3 1 0 0: 4 ways (4 ways to choose the odd one out)
2 2 0 0: 3 ways (AB, AC, AD, BC, BD, CD total 6 ways in the first box but we have to divide by 2 as AB CD is the same as CD AB and there is double counting)
2 1 1 0: 6 ways (AB, AC, AD, BC, BD, CD total 6 ways)
1 1 1 1: 1 way -
:thankyou:
Quekcc for the clear explanation .so it's not putting different marbles in each box.
Sorry blur me.. Missed out mathsolympiadtrainer's post. Thank you very much for your explanation too! -
Anyone’s kid participating in the GAUSS MO contest this May? DS is registered for Grade 7 but I see that the Sect C qns are beyond P3 syllabus. He won’t be able to ans those as he’s not taught geometry and other advanced topics. What level (relative to local primary std) is grade 7? Thx

If I'm not wrong, Grade 7 = Sec 1 -
Thanks dagong99. No wonder for sect C, the qns looked unfamiliar. In fact sect B oredi had some qn beyond ds’s comprehension.
