1) 1/(11!/2!*2!) = 4/11!
2) 1/(49c6) i assume that order does not matter. 123456=654321. but i think the question is not properly phrased.
Hey, this is same as your previous answer:
1/49C6 = 6! x 43! / 49! = 6! / (49x48x47x46x45x44)
Your previous answer was also correct.
oh right ! too late here in germany
you can approach this problem with combination- as well as with permutation-reasoning...
If your mind can conceive it and your heart can believe it, have faith that you can achieve it.
