Afamily decides to have children until it has three children of the same gender. assuming p(b)=p(g)=.5,. what is the pmf of x = the number of children in the family? . this problem was in the section of negative binomial distribution in the textbook and i used the equation for nb but the sum of all the probabilities is just 0.5. and, i saw in yahoo someone using the p(a)= n(a)/n and getting the sum of p(x)=1. also, it made sense for this problem as both the events were equally likely-- p(b)=p(g)=0.5. but, shouldn't nb also give the same result as of using the classical definition?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
