It is commonly assumed that 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 probability they have one boy and one girl?

49.97% probability they have one boy and one girl.

Step-by-step explanation:

For each children, we have these following probabilities

0.513 = 51.3% probability of being a boy

1-0.513 = 0.487 = 48.7% probability of being a girl

If a family has two children (not twins), what is the probability they have one boy and one girl?

It can be either a boy and then a girl, or a girl than a boy.

So

49.97% probability they have one boy and one girl.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
