Question 9(Multiple Choice Worth 1 points)(06.04 MC)The figure below shows a shaded rectangular region inside a large rectangle:O 8%2 units16%4 units10 unitsWhat is the probability that a point chosen inside the large rectangle is not in the shaded region?5 units

Answer 1

The required probability is given by the:

$100\%-\frac{Area\text{ of the shaded rectangle}}{Area\text{ of the largest rectangle}}$

The area of the largest rectangle:

$5\times10=50\text{ square units}$

The area of the shaded rectangle:

$4\times2=8\text{ square units}$

Hence, the required probability is given by:

$100\%-\frac{8}{50}\times100\%=100\%-16\%=84\%$

Therefore, the required probability is 84%.
