Step-by-step explanation:
We can even break this down further by simply only looking at the total amount of males, and finding the proportion of males that are divorced, which is , the same value.
Note that P(Male | Divorced) means the probability of choosing a male, given (|) that person is divorced.
The result is
9
a
2

16
The reason is the following:
The problem is an example of a notable product: "the sum multiplied by the diference is equal to the difference of squares", that is to say:
(
a
+
b
)
⋅
(
a
−
b
)
=
a
2
−
b

.
By applying this to our question, we obtain that:
(
3
a
−
4
)
⋅
(
3

)
=
