In a family of five children what is the probability that… Two are males and three are females

Okay. So this is the same type of problem again in a family of 5 children, so we need to use this line from the Pascal's Triangle. No idea what I'm talking about. Watch the questions before. And this time it's asking, what are the probability that 2 are males, 3 are females? Remember, a equals male, and that equals 1 half because there's a one half chance of having a male. B equals female, and that also equals 1 half because there is a one half chance of having a female. And so, if 2 are males, it's not gonna be this one because it says that all 5 are males. This one says that 4 are males and 1 is a female, not it. This one says that 3 is a female and or 3 is a male and 2 is a female, so that's not gonna be it. This is going to say that, 2 are males and 3 are females. So this is the appropriate, formula. So when we put in the appropriate numbers, you've formula. So when we put in the appropriate numbers, we put in 1 half for each of the following things and we solve for it. What is it? I got your calculator. If you don't know, if you watched question 1, you probably already know what it is. And giving you some time to solve that, it is also a 31%. So the 31% chance that if in a family of 5 children, 2 are males and 3 are females. So hopefully, with these practice problems, you're understanding how to use the, Pascal's Triangle to solve these, probability problems, in terms of genetics. So with that, let's now turn the page.
