The answer is D. There's a 5/9 chance of picking a girl, but the principal has to pick twice, making it a 5/18

Your answer is D. Explanation: 5 girls plus 4 boys is 9 and so the fraction you will be getting is 5/9. So your chance is a 5/9 chance that the first choice for the morning announcement is girl. But since the principal is choosing 2 times, you have to double the denominator and not the numerator because you are not adding to the amount of girls in the class. Therefore your answer will be 5/18.
