Hello there!
The answer is:
-5/8
-0.75
7/8
The answer is 62/95. You determine this by calculating the probability of both students being girls.
Probability first student is girl: 12/20
Probability second student is girl: 11/19
Multiply 12/20 * 11/19 = 132/380 or 0.347
Probability of both students not being girls: 1 - 0.347 = 0.653 or 62/95
