Have you drawn a Venn Diagram?The question:
Employment data at a large company reveals that 72% of the workers are married, that 44% are university graduates and that half of the university graduates are married. What is the probability that a randomly chosen worker...
a) is neither married nor a university graduate?
b) is married but not a university graduate?
c) is married or is a university graduate?
I tried to convert the wording into math as follows,
Let M = "people married"
Let G = "people graduated"
a) We want to find , so:
Thus we get 0.28 x 0.56 = 0.1568
However, this is incorrect. I'm sure I've made a wrong assumption somewhere. I'm yet to attempt part b) and c) since I'm not sure where I've gone wrong with a). Any assistance would be great.
