Answer:
1/2.
Step-by-step explanation:
There are 2 quadrilaterals which have 4 congruent sides in the list: A square and a rhombus, The square is the one with four right angles.
So the required probability is 1/2.
The probability that the shape has four right angles, given that it has four congruent sides is 1/2.
What is probability?
Probability is the ratio that shows the likelihood of an event occurring from a given set of other events.
It is given that there are 5 shapes.
There are 2 shapes that have congruent sides. They are rhombus and square.
There are 2 shapes that have right angles. They are the square and the rectangle.
P( shape has four right angles, given that it has four congruent sides ) = number of shapes with four congruent sides and four right angles/number of shapes with congruent sides = 1/2
Therefore, we have found that the probability that the shape has four right angles, given that it has four congruent sides is 1/2.
