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*10=50\text{ square units}`

The area of the shaded rectangle:

`4*2=8\text{ square units}`

Hence, the required probability is given by:

`100\%-(8)/(50)*100\%=100\%-16\%=84\%`

Therefore, the required probability is 84%.
