Answer:
![\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B20%7D)
Step-by-step explanation:
We want probability that 1st is girl AND 2nd is girl as well.
In probability "AND" means multiplication and "OR" means "addition".
<u><em>We find the probabilities separately and multiply them together, since "AND".</em></u>
<u><em /></u>
- P(girl from 7th grader) = number of girl 7th grader/total number of 7th grader
=9/10
- P(girl from 8th grade) = number of girl in 8th grade/total number of 8th grader
=2/4
P(both girls) = 9/10 * 2/4 =9/20
