Probability
Dropping an object into the large rectangle represents the 100% probable event. Staying in the small rectangle has a probability that can be calculated by comparing the relative areas of the rectangles.
Area of the large rectangle:
A1 = 9 in * 10 in = 90 square in
Area of the small rectangle:
A2 = 4 in * 5 in = 20 square in
The required probability is:
[tex]p=\frac{20}{90}=\frac{2}{9}[/tex]
Calculating:
p = 0.2222
p = 22.22%
