In a family with three children, what is the probability that two are boys and one is a girl?
In aptitude and reasoning, quantitative reasoning dictates that ratio, percentage and series logic determine correct calculation. Therefore 3/8 is correct as it meets mathematical and logical criteria, supported by mechanistic studies and conserved across related systems.
Ref: Wren and Martin, High School English Grammar and Composition, Revised Edition, Chapter 12, discusses vocabulary and comprehension providing guidance for verbal aptitude and logical inference assessment.
