(1 point)
A. 213 girls out of 850 kids
B. 425 girls out of 850 kids
C. 567 girls out of 850 kids
D. 607 girls out of 850 kids
The ratio of boys to girls is 2 to 4, which can be simplified to 1 to 2.
To find the expected number of girls, divide the total number of students by the sum of the parts in the ratio (1+2=3) to find the part of the ratio representing the girls.
Expected number of girls = (2 parts / 3 parts) * 850 kids = 567 girls.
Answer: C. 567 girls out of 850 kids.
