Probability - very Interesting topic

a Friend asked me a puzzle: "I have two children. One is a boy born on a Tuesday. What is the probability I have two boys?"

I answered based on my thinking process. My thinking direction was correct but maths for it was very wrong. What do you think answer is? Any idea?

In my next post, I will share the link which gives its answer... enjoy!!!

P.S. My last post about "Possibility of accident" -- has bad maths to calculate probability :) Now I know why... ;-) But chalta hai.... kaun certificate dene wala hai ;-)

cheers

mmm.. think 1/4 if both are unknown

Since one is known, it should be 1/2...

Well... inspired by ur words on whoz gonna a give a certificate ;)

It's simple .. Probablity is 1/2 of getting a boy ( or even a girl) ..

This outcome does not depend on the previous one .. So it becomes a simple math ..

Did you guys take science in 11th-12th ? you studied Probability ... right ? ;-)

Wrong Answer!!!

Don't think it's that simple... but yeah it's not too complicated.. I will post the link soon.
