Answer:
See below.
Step-by-step explanation:
It is known that a parallelogram has rotational symmetry, rotated 180 degrees about it's center point. Now by definition a parallelogram is a quadrilateral with two pairs of parallel sides, hence it's name. If you were to take a look at the attachment below, you might see the connection.
Rotational Symmetry will make it so that side AB corresponds to CD, respectively AD and CB. The sides will coincide with one another after a 180 degree rotation, so that AB = CD, and AD = CB. Hence, in the same parallelogram, opposite sides are congruent.

Using it's concept, it is found that there is a 0.79 = 79% probability that he or she is content with the vacation allowance.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, 500 - 105 = 395 out of 500 employees are content with the vacation allowance, hence:
p = 395/500 = 0.79.
There is a 0.79 = 79% probability that he or she is content with the vacation allowance.
