The probability should still be 2 out of 10 even if it's random. No matter what he's just trying to get 2 questions right. Other than it being completely random. So 2/10 or 1/5. That's what I would say. If they say different you could argue that more information is needed.
Answer:
C. (-3,6)
Step-by-step explanation:
Take 10x + 7y = 12 as first equation and 8x + 7y = 18 as second equation.
Subtracting both equations, you will get
10x + 7y - 8x - 7y = 12 - 18
2x = -6
x = -3
Substitute value of 'x' in any of the given equation :-
10x + 7y = 12
10 * -3 + 7y = 12
7y = 12 + 30
y = 42/7
y = 6
