Answer:
A.
Step-by-step explanation:
Given:
The regular polygon is a decagon having 10 sides.
Perimeter of the given polygon is,
.
We know that, perimeter of a regular polygon of sides is given as,
where,
is the length of each side.
Here,
Plug in these values and solve for . This gives,
Therefore, the side length of the given polygon is
Answer:
.
Step-by-step explanation:
We use the Venn diagram to calculate the desired probabilities.
Note that there are 6 possible results in the sample space
S = {1, 2, 3, 4, 5, 6}
Then note that in the region representing the intercept of A and B there are two possible values.
So
In the region that represents event A there are 4 possible outcomes {4, 5, 1, 2}
So
In the region that represents event B there are 3 possible outcomes {1, 2, 6}
So
.
Now
