Sir, In 2nd last question, how can it be sure that two blue pens were drawn in first attempt only? Can't there be possibility of drawing 1 blue pen & 1 black pen in first attempt and then 1 blue pen in the 2nd attempt? I think the statement of this question needs to be precise. please reply.

sir mera ans to 3/7 aa rha hai or mera hi nahi bahoot students ka yahi ans aa rha hai so please sir clear this doubt....

[@mohitpathak5472]

Yeah...even i have the same doubt!!! Yaha par permutation vala concept bhi lgna chahiye as different orders are possible. Aur agar ham same chiz last question me kre to answer 1/7 ki jagah 3/7 ban jayega as there will be 3 different ways in which 2 chocobars and 1 ice-cream can be withdrawn. So 1/7+1/7+1/7 = 3/7. But ye clear nhi hai ki yaha different order consider karne hai ya nhi????
