Puzzle from India
I was enroute from India to USA when I got a call from one of my nephews with the following math problem he was stuck with. I am posting that as the puzzle of this week.
There is a jar with 50 pieces of paper written “1” thru “50” in them. You pick 5 of them at random and lay them out in increasing sequence. What is the probability that the middle number is 30?
Kon class ey nephew? :@
1 out of 50 (from Steve)
i was going to say 0.036408 but this says “Puzzle from India” so there must be a catch. 🙂
There is no catch. That is the answer. Deepak, yours is the same too.
29c2 x 20c2 / 50c5 ?
Do you think that standard of Indian schools are at par with that of U.S.A?
