<span>The correct answer is 1/78.
Explanation<span>:
There are 2 orange marbles out of 13 total marbles, so the probability of your first marble being orange is 2/13.
After this one is drawn, since it is not returned, the probability of getting a second orange marble is 1/12, since there is only 1 orange marble left out of 12 total marbles.
This gives us the total probability 2/13(1/12)=2/156=1/78.</span></span>
X =(6-√124)/4=(3-√ 31 )/2= -1.284
x =(6+√124)/4=(3+√ 31 )/2= 4.284
(2x2 - 6x) - 11 = 0
