How many people must be gathered together in a room, before you can be certain that there is a greater than 50/50 chance that at least two of them have the same birthday?

Take 9 from 6, 10 from 9, 50 from 40, and leave 6.

How Come ??

I get hot but I never sweat,
I cook food but I am not a chef,
I have a door but you can't enter me,
I have a light but I am not a lamp.
Who am I?

I am taken from a mine and shut up in a wooden case, from which I am never released, and yet I am used by almost every person. What am I?

Can you find a five letter word that is left with only two letters if one is removed?

I speak without a mouth, and hear without ears. I have no-body, but I come alive with the wind. What am I?

All of you like to eat me. I am a five-lettered word. Remove the first two and I turn into an infamous animal. Remove just the first and I become a heinous crime. Remove the first and the last and you can groove on me.

Can you guess who am I?

People make me, save me, change me, raise me. What am I?
