i have some Biology HW... i just don't understand it...
Can anyone here help me with questions like "what are the probabillity of a family having three daughters?"
anyone want to help? Please :)
-peace
i'll post the questions if someone here knows how to do this type of stuff, i just don't get it :confused:
Lol, asking on a cannabis forum for help with your homework? :p
Your ALMOST as crazy as me. I cant help you, im dumb.
Mybe you could ask parents?
there are some intelligent people here, definately.
My parents wouldn't know, maybe i'll ask my older brother... :-(
There are 2 types of sexualality, male and female.
There is a 50% chance to have a female or male during each conception.
So there is a 50% chance to have 3 daughters or sons.

ask away dude, i got an A in biology
Wait, I lied.
1/2 x 1/2 x 1/2. = 1/8th of a chance. ahha.

On a calc just divide 1 by 8 and that should be it.

If I remember right from biology it just depends on which sperm makes to to the egg. Ones carry the x chomosome and the other carries the y chomosome. So as to probability I dont know if that can be determined. I think that would have to be done on a higher level of population studies then divided by the number of all females only to a set of parents to derive a mathematical equation of probablility.
I think he's in reg 9th grade or 10th grade bio. They assume perfect everything, so (1/2)cubed.
