I just did this practice exam, and I was curious what am I missing.

In practice exam 2, Q3 the suggested answer is incorrect and correct answer should be 18/35 or 0.51.

According to suggested answer, 24/35 = 0.685, the probability of getting a boy is higher than for either boy or girl which is impossible.

This has now been corrected - it is 18 / 35.
