Results from our forumProbability Genetics question... for bbbb. But for others, it changes: For example for 1 g and 3 b its: gbbb: 6.25 % bgbb: 6.25 % bbgb: 6.25 % bbbg: 6.25 % Total: 25 % As using binomial expansion it's: (g+b)^4 = g^4 + 4(g^3)b + 6(g^2)(b^2) + 4g(b^3) + b^4 2 boys and 2 girls = 6(g^2)(b^2) = 6 x 1/4 x 1/4 = 0.375 which is 37.5% ...

Probability Genetics question... four children can we expect to have two boys and two girls? I know its a 50% chance of each (for the purposes of this problem). I am asked to use binomial expansion to solve. I underlined the percentage of families because that is where it differs from all the other problems I've encountered thus ...

Re: Biology statistics problem: binomial with non-constant pI did a poor job of explaining myself. Suppose 100 events/trials, each with a different (and known) frequency of success (p). I want to calculate the probabilities of the 100 trials resulting in 0 total succesful trials, 1 total successful trial, 2, 3, ... 99, and 100 total successful trials.

Biology statistics problem: binomial with non-constant p... to increase by half an hour, which is unacceptable. That's when I started looking into trying to calculate this curve. From what I've read, the binomial distribution is clearly what I want, except for one thing, it assumes p is constant. In my problem, every p is different. Is this possible ...
