Out of 7 childrens, the youngest one is boy, what is the probability of the remaining 6 are also boy?

• probablity of being a girl is 1/2 and being a boy is 1/2
  there fore probablity of remaining six boys are=(1/2)*(1/2)*(1/2)*(1/2)*(1/2)*(1/2)=1/64......!!
• 12 years agoHelpfull: Yes(17) No(2)
• 1*(1/2)*(1/2)*(1/2)*(1/2)*(1/2)*(1/2)=1/64
• 12 years agoHelpfull: Yes(5) No(1)
• probability of the remaining 6 are also boy= (1/2)^6
• 12 years agoHelpfull: Yes(4) No(0)
• because the children to be a girl or boy is independent.
  hence probability of remaining 6 to be boy is
  (12)^6
• 12 years agoHelpfull: Yes(2) No(0)
• 1/(2^6)=1/64
• 12 years agoHelpfull: Yes(2) No(0)
• Ans is: (1/2)^6
  Probability is 1 out of 2. Since one boy is selected out of 7 children, remaining is 6.
  Hence, probability is (1/2)^6
