Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.
Event A - get a green or yellow marble
Event B - get a pink marble
Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.

Probability of combined events is
Answer:
Proper fraction
Step-by-step explanation:
If the numerator is less than the denominator , then it is proper fraction.
Example : 
Answer:
Choice D
Step-by-step explanation:
Several techniques do exist for solving systems of linear equations; substitution method, graphical method and elimination method. For this scenario, since we are not restricted on the method, I opted to use the graphical technique.
The graphical solution to a system of linear equations is the point where the lines intersect. If the lines are never intersect then the system has no solution.
The attachment below shows that the system intersects at the point (-3, 26). Therefore, the system has a single solution: x = -3, y = 26.
Angle B would be equal to angle E
