Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four e

Alexxx [7]

Answer:

0.25

Step-by-step explanation:

This is the question on conditional probability

Let A - the quadrilateral has four right angles

B - the quadrilateral has four equal side lengths

Required probability = P(B/A)

By definition of continuous probability

$P(B/A) = \frac{P(AB)}{P(A)}$

$P(AB) = \frac{2}{20} =0.10$

P(A) = $\frac{8}{20} =0.4$

Hence given probability = $\frac{0.1}{0.4} =0.25$
