-5x² - 6 = -4x
-5x² + 4x - 6 = 0
a = -5 ; b = 4 ; c = -6

= 16 - 120
= -104

using the above form formula.
;
From the given table, we have the values of P(A), P(D), and
.
Since, Probability=
∴,
,
and
Now, putting these values in above formula we get,
.
As, you can see above that the values of P(A|D) and P(D|A) are not equal.
