Read Solution (Total 4)
-
- 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 - 13 years agoHelpfull: Yes(16) No(0)
- 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 - 13 years agoHelpfull: Yes(7) No(2)
- this is simple
1/(2^(n-1)=1/2^6
which is 1/64 - 13 years agoHelpfull: Yes(5) No(0)
- 1/2*1/2*1/2*1/2*1/2*1/2=1/64
