Really need im struggling
bart found 20 quadrilaterals in his classroom. he made a venn diagram using the properties of the quadrilaterals, comparing those with four equal side lengths (e) and those with four right angles (r).
given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four equal side lengths? express your answer in percent form, rounded to the nearest whole percent.

At Venn diagram there are 4 parts (20 pieces):

1. Colored only in blue - quadrilaterals with four equal side lengths (3 pieces);

2. Colored only in orange - quadrilaterals with four right angles (6 pieces);

3. Colored in both blue and orange - quadrilaterals with four right angles and with four equal side lengths (2 pieces);

4. Colored in white - quadrilaterals withoutprevious two properties (9 pieces).

Consider events:

A - a randomly chosen quadrilateral has four right angles;

B - a randomly chosen quadrilateral has four equal side lengths;

Use formula to find the probability that a randomly selected quadrilateral with 4 right angles also has four equal side lengths:

Pr=0.25
