Draw a Venn diagram with two intersecting circles inside a rectangle
---
Let the total in the rectangle = 100
The intersection of the 2 circles has 44
The 1st circle has 76-44 = 32
The 2nd circle as 54-44 = 10
----
1st OR 2nd = 10+32+44 = 86
----
Your Problem:
P(1st OR 2nd)' = 100-86 = 14
-----
Ans P(1st OR 2nd)' = 0.14
