The figure below shows a shaded rectangular region inside a large rectangle:
2 answers:
First we need to find the areas of both rectangles.
And area of larger rectangle = 10*5=50 square units
Area of smaller rectangle = 7*3 = 21 square units
Area between the two rectangles, = 50-21=29 square units
And since, we have to find the probability that a point is choosen is not in the shaded rectangle that is the smaller rectangle, so it means we have to find the probability of the point is choosen in the area between the two rectangles . Therefore,
Required probability =
Therefore correct option is the second option .
