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 .

We have been given the function
We know that the range is set of y values for which the function is defined. Therefore, we will find the value for x and then observe the restriction is y's values.
Now, we know that logarithm function is not defined for negative values. Hence, the value for y is always greater than zero.
Therefore, the range of the function is given by y>0
B is the correct option.
