57. Out of 7 children the youngest is boy than find the probability that all the remaining children are boys?

• The Probability of a boy or a girl equals 1/2
  Now the youngest is already a boy so the probability that the remaining are boys is= 1/(2^6) (As for now only 6 children are left)

• 1/64
  sample space is 2 for 1 boy or girl
  1 is predetermined boy
  so left 6 (1/2)*(1/2)*(1/2)*(1/2)*(1/2)*(1/2)
  =>1/2^6 =1/64
