Answer:
The answer is the square pyramid.
Step-by-step explanation:
The square pyramid is a solid figure that its base is a square and his height is conformed of four face which converge to one point.
I have attached an image that shows a square pyramid and a counting of every edge and vertice.
The rectangular prism and the pentagonal prism have more edges and vertices. On the contrary, the triangular pyramid has less vertices and edges.

Answer:
And we can find this probability with this difference:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the amount of cofee shops of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference:
