Please refer to the attached image.

-2/5, 4/5 and -2/5 + 4/5 have been marked in red in the image

The points marked on the number line are separated by a distance of 1/5.

So when you add 4/5 to -2/5 you need to move 1/5 4 times (4/5 = 4 x 1/5) towards the right to reach the SUM.

Based on this, the sum of -2/5 and 4/5 is 2/5, and has been highlighted in the image.

Find P(A or B) if the events are disjointed. P(A) =6/25 , and P(B) =9/25 .
nevsk [136]
Here, "disjointed" signifiies that Event A and Event B are independent; neither outcome influences the other.  In such a case, the union of A and B is given by the sum of the two probabilities P(A) and P(B).

Here, that sum is P(A or B) = 6/25 + 9/25, or 15/25, or 0.6.
