We know that the total percentage of those who agree is 36.2% and

this includes those who also have a university degree or higher.

So to find those who agree, but don't have a university degree,

we subtract the two probabilities and find that 32.6% of

people agree with the statement, but don't have a university degree.

Similarly, 13.8% of people have a university degree or

higher, and taking out those who also agree with the statement

leaves us with 10.2% of people who disagree with the statement but

have a university degree or higher.

Next we want to find the probability that a randomly drawn

person has a university degree or higher or

agrees with the statement about men having more right to a job than women.

Let's also put back on the screen what we know so far.

We're looking for the probability of agree or university degree.

And that should remind us the general addition rule, probability of A or B is

equal to probability of A plus probability of B minus probability of A and B.

Or, in context, probability of agree plus probability of university

degree minus probability of agree and university degree.

From here onwards, we can just plug in the probabilities that we already know.

That's 0.362 for P of agree, 0.138 for

P of university degree, and -0.036 for

the intersection, resulting in 0.464.

So there's about a 46% chance that a randomly drawn person has

a university degree or higher, or

agrees with the statement about men having more right to a job than women.
