Answer:
(a) Disjoint
(b) Independent
(c) No
Explanation:
(a) Disjoint events are those events that are mutually exclusive or we can say that the two events can not occur at the same instant.
Thus in a single draw we can not get both yellow and green ball.
(b) Those events in which the probability of the occurrence of one event does not affect the probability of the happening of another event in any way.
Thus the two pieces drawn are from the infinite supply does not affect one another and hence are independent.
(c) No, since after one event has occurred the occurrence of the other one is not possible.
2x+7y=4
+(-2x-8y=-2)
------------------
0x-y=2
-y=2 (this is the result of adding the two equations)
But...
y=-2
2x+7(-2)=4
x=9
