Hi guy and girls,, i have the probabily problem i'm trying to work out, it's the odds of this happening is the anwser to this problem and i'm stumped on this one.,

Hope you can help and thanks in advance

ok my family on my mothers side is 5 brothers and 4 sisters, the siblings are 7 boys and 9 girls

None of the family members are left handed, all are right handed

of the siblings all the boys (7) are left handed and all the girl(9)s are right handed

what are the odds of all the boys being left handed when there was not an expression for it in the family members

i hope i can get to the bottom of this one

Kind Regards

Barry
