At Chico's school, 60% of the students are boys, and 40% are girls. 10% of the boys play soccer, and 20% of the girls play soccer. Chico is making a diagram to represent the probability that a student chosen at random is a girl who plays soccer. What should he do to complete the diagram? An area model with 100 squares. 60 squares are blue and 40 squares are pink. CLEAR CHECK Shade 20% of one of the pink squares. Shade 20 pink squares. Shade 2 of the 10 rows in the pink section. The model is complete, so just count the pink squares
