Please help me for this problem.
I have a 6 digit number : 1 2 3 3 4 5
I want to know in how many ways can I form a number which is greater
than 200000 but which is odd. Some of my friends tell me the answer is
216 but others insist it is 204. Please explain your reasoning too
along with your answer.

And caan anyone help me in some way to solve the hardest of all
permutation andd combinations. Just give me some tips on how to solve
them and how to break a problem into smaller parts and identify it
well and solve it correctly.
