Sinus hominem has cranial features that include a 1520 cc braincase, and enlarged nose passage for living in cold climates.
There are 4 pairs of sinuses. These are the frontal, maxillary, ethmoid, and sphenoid sinuses (not shown). Blocked sinus openings block the flow of mucus and increase pressure, causing pain and inflammation.
Maxillary Sinus: The largest of the maxillary sinuses, located behind the cheekbone near the cranial features. Sphenoid Sinus: The sphenoid sinus is located in the sphenoid bone near the optic nerve and pituitary gland on the side of the skull.

Given:
62% of the residents visit Comet Mall.
73% of the residents visit Star Mall.
48% of the residents visit both malls.
To find:
The probability that a resident chosen at random shops at either Comet Mall or at Star Mall.
Solution:
Let A be the event that the residents visit Comet Mall and B be the event that residents visit Star Mall. Then, we have



We need to find the probability that a resident chosen at random shops at either Comet Mall or at Star Mall. It means, we have to find the value of
.
We know that,

On substituting the given values, we get


Therefore, the probability that a resident chosen at random shops at either Comet Mall or at Star Mall is 87%.
