Answer: The required probability is 25%.
Step-by-step explanation: Given that four books, one each on physics, chemistry, mathematics, and biology are about to be stacked on a shelf.
We are to find the probability that the mathematics book is on top if the books are stacked randomly.
Let, 'M' be the event that the topmost book is of mathematics.
Then, n(M)=1.
Let 'S' represents the sample space for the experiment.
Then, n(S) = 4.
Therefore, the probability that the mathematics book is on top is given by
Thus, the required probability is 25%.

On solving the question, we got that - The dimensions of the rug should be 18 feet and 24 feet
<h3>What is area of rectangle?</h3>By multiplying the rectangle's length by its breadth, we may get its area.
Equiangular quadrilaterals, like rectangles, are known in this way. This is so because a rectangle is a four-sided quadrilateral shape with parallel sides that are equal to one another and four corners with 90o angles. Rectangles are sometimes known as equiangular quadrilaterals since all of its angles are 90 degrees.
the parameters provided;
The room is 20 feet by 26 feet in size.
432 feet2 is the largest area rug she can afford.
If the floor will be a uniform stripe around the rug, then each dimension should have its uniform extra length of floor = (y).
here, a= 1, b= -46, c =88
Therefore, Length = 20-2 = 18 ft
and width = 26-2 = 24ft
