Most people think babies are equally likely to come as either a boy or a girl. This is not true. Actually, about 51.3% of all babies are boys. If a family has two children (not twins), what is the chance they have one boy and one girl

0.499662

Step-by-step explanation:

Now since 51.3% of all babies are boys, this means that the probability of having a baby boy P(b) = 51.3/100 = 0.513

Since there are only two options, you are either a boy or a girl. The Probability of having a girl child P(g) = 1 - P (b) = 1 - 0.513 = 0.487

Now, we proceed to calculate the probability.

The probability of having one boy and one girl = probability of one boy and one girl or probability of one girl and one boy

Or in probability means that we have to add the two possibilities together.

P = (0.513*0.487) + (0.487 * 0.513) = 0.499662

i believe the answer is the polygon, heptagon.

well the answer to that is xoxoxo
