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

6-1/3x=-1 How do I do this
I am Lyosha [343]
Im gonna assume you mean 6 - (1/3)x = -1.  Your notation is not super clear.  If so, solution is as follows:

6 - (1/3)x = -1   [subtract 6 from both sides]
-(1/3)x = -7       [multiply both sides by -3]
x = 21
