Answer:
Q
Step-by-step explanation:
5x+15y ≥ -20
Solve for y
15 y≥ -5x-20
Divide by 15
y ≥ -5x/15 -20/15
y ≥ -1/3 x -4/3
Y is greater than or equal to so shade above and on the line
4x-2y > 6
Solve for y
-2y > -4x+6
y < 2x -3
Shade below the line
The double shaded area is the solution
The answer is (5/10)*(4/9)=20/90= 2/9
because there are 5 red marbles out of a total of ten. if you take one out then there are 4 red marbles out of a total of 9. The probability of these events being in succession is the product of their probabilities.
