Response:
Second option: 
Third option: 
Detailed explanation:
The missing graph has been provided.
The attached image illustrates the graphing of the following system of linear equations:

Notice the intersection of the lines.
According to the definition, if lines in a system of equations intersect, then there is only one solution. This implies that the intersection point is the solution to that system. This can be expressed as:

Represented by "x" for the x-coordinate and "y" for the y-coordinate.
Here, it's noticeable that:
- The x-coordinate of the intersection point lies between
and
.
- The y-coordinate of the intersection point is situated between
and
.
Therefore, you can conclude that the forthcoming points (Refer to the options given in the exercise) are potential approximations for this system:

Answer:
A student who plays a sport but does not watch rugby is selected from those who engage in sports.
Step-by-step explanation:
"Determine the probability that a randomly selected student from the sports-playing group does not follow rugby."
90-15= 75 individuals either participate in sports OR follow rugby.
65+71-75=
136-75=
61 individuals play a sport AND are rugby watchers.
14 individuals are involved in sports but DO NOT follow rugby.
is the probability of picking a student who is part of sports but does not watch rugby from the sports group.
