The probability that a point is not on AB is the probability that a point is on BC

The probability that a point is not on AB or CD is 5/14

How to determine the probability?

From the figure, we have the following parameters:

AD = 28

AB = 12

BC = 10

CD = 6

if a point is not on AB or CD, then the point would be on BC

This means that we calculate the probability that a point is on BC

So, we have:

P(BC) = BC/AD

This gives

P(BC) = 10/28

Simplify

P(BC) = 5/14

Hence, the probability that a point is not on AB or CD is 5/14
