Note that 7 represents each of the different 7 regions in the spinner.
1 would represent the red region, as there is one red region.
4 would represent the 4 green regions. Thus, 2 represents the 2 blue regions.
Note that as the spinner spins, no matter which region is colored with which color, the probability of hitting a blue region is
, as out of 7 regions we can hit, 2 are blue.
(Naturally enough, the greater the number of regions of a certain color, the greater the probability of hitting a region of that color.)
7 is the number of the elements in the sample space.
2 is the number of the elements in the event: "hitting blue".
This probability, as mentioned earlier, is matched by the outcome "hitting blue."

We have been given an inequality . We are asked to choose the solutions of our inequality from given choices.
The solution of inequality are all values of x greater than 38.
Let us see our given choices one by one.
A.
Since solution of inequality is greater than 38 and 25 is less than 38 , therefore, 25 is not a correct choice.
B.
Since the solution of inequality is greater than 38 and 40 is greater than 38, therefore, 40 is the correct choice.
C.
Since the solution of inequality is greater than 38 and 120 is greater than 38, therefore, 120 is the correct choice.
Hence and
are solution for the given inequality.
