Option b) 
Step-by-step explanation:
We are given the following information in the question:
Total number of marbles = 65
Number of green marbles = 17
We have to find the probability of drawing 2 green marbles at random without replacement.
Formula:




Option b) 
Answer:
(-1,7)
Step-by-step explanation:
-9x + 2y = 23
-4x - y = -3
multiplying equation 2 by 2
-9x + 2y = 23
-8x - 2y = -6
adding the two equation to cancel out y
-17x = 17
x = -1
plugging back x = -1 into the second equation
4 - y = -3
-y = -7
y = 7
