Help please! Explain your answer! To select two students to read the morning announcements, the principal places 5 girls names and 4 boys names in a bag. What is the probability that both students selected to read the morning announcements will be 2 girls?

A. 1/81
B. 1/36
C. 1/6
D. 5/18

Respuesta :

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.
