andrew27 Posted October 30, 2008 Share Posted October 30, 2008 You come from a family of 6 children consisting of 3 boys and 3 girls. You plan on having 6 children. Assuming you do that what is the probability that you will also have 3 girls and 3 boys. Link to comment Share on other sites More sharing options...
NeonBlack Posted October 30, 2008 Share Posted October 30, 2008 (edited) Since you put this in Genetics and not math, I'll assume this is not homework. You come from a family of 6 children consisting of 3 boys and 3 girls. This has nothing to do with future results. Assuming the chances of having a boy or girl are equal, the odds of having a total of 3 of each is about 31%. If you want an explanation, you will have to convince me that this is not homework.

Mr Skeptic Posted November 2, 2008 Share Posted November 2, 2008 There is a homework help forum, and people are more likely to help when you don't insult them by insinuating that they are too dumb to tell a homework question when they see one. We are willing to help you understand, but we are not here to spoon-feed you answers. Here's the equation you want. Ask if you do not understand it. [math]Probability = p^iq^{n-i}\frac{n!}{i!(n-i)!}[/math] where p is the probability of the first result, q is the probability of the second result, i is the quantity of the first result, (n-i) is the quantity of the second result Link to comment Share on other sites More sharing options...
