out of 7 children the youngest is a boy then find the probability that all the remaining children are boys.

• 1st one being boy probability (1/2)
  the second one with respect first one is (1/2)(1/2)
  in this way goes as the seventh one is boy so the probability will be (1/2)^6

• prob of being a boy=1/2
  youngest being a boy prob of remaining being a boy=1*(1/2)raise to power 6
  i.e=1/64 ans

• this is simple
  1/(2^(n-1)=1/2^6
  
  which is 1/64

• 1/2*1/2*1/2*1/2*1/2*1/2=1/64
