6.there are 12 children in a family .the youngest 1 is a boy.then find the probabality
of finding boy in the family.
a)4096
b)2048
c)2
d)2!

• Probability cannot be more than 1..it ranges from 0 to 1..
  there can be two options..either a boy/girl in a family
  asked is to find a boy=1/2
  given 12 children but it is already mentioned that the youngest is a boy so no need to count that..
  hence,1/2*1/2*1/2......(11 times)=1/2048 option b..but the option is wrong..it should be 1/2048

• all the option given is wrong,first thing always keep in mind that probability can not be greater than 1.
  so answer will be (1/2............11 times)=1/2048(ans)
