A family has two children. Find the probability that both children are girls, given that at least one of the two is a girl who was born in winter. Please assume that (i) gender is binary, i. e., a boy or a girl, (ii) P (a boy) = P (a girl) = 1/2, (iii) genders of the two children are independent, i. e., knowing one’s gender gives no information about the other’s gender, (iv) four seasons are equally likely, and (v) gender is independent of season.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
