A brother and a sister are in the same math class. There are 8 boys and 10 girls in the class. One boy and girl are randomly chosen. What is the probability that the brother and sister are chosen? Write your answer as a fraction in simplest form.

45.3592

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
