Find the probability that marble will come to rest in shaded portion of the base
![Check Mark](/static/check-mark.png)
Answer to Problem 75E
The probability is
Explanation of Solution
Given:
The probability that the marble will come to rest in the shaded portion of the base is equal to the ratio of the shaded area to the total area of the figure.
Consider the above figure
In which the sides of the bigger rectangle is
Also consider that,
The area of the bigger rectangle
Also, the area of the smaller rectangle
Given, the probability that the marble tossed will end up at rest in the shaded portion is equal to the ratio of the area of shaded region to the area of the total figure.
Hence, the probability is
Where,
