Answer:
1. 68/89
2. 46/267
Step-by-step explanation:
1. The total number of people in drama or athletics can be found by adding up all categories where a person fits at least one of the criteria:
51+11+12+15+108+7=204
Now we need to add up the total number of people in all categories:
51+11+12+15+108+7+63=267
Finally, we divide the total number of people in either drama or athletics by the total number of people in all categories:
204/267 = 68/89
2. The total number of people in athletics and drama can be found by adding up all categories where a person fits both criteria:
15+12=27
The total number of people in music and athletics can be found by adding up all categories where a person fits both criteria:
7+12=19
Now, we add both of these numbers together and put it all over the total number of people:
27+19=46
46/267
The solution of x in the given expression 
is 4. However, if it is 
, it is 6.
<h3>What is the solution to algebraic expression?</h3>
The solution to the given algebra expression involving surds can be seen in the steps below.
Given that:
Remove the square roots, we have:
12x - 32 = 4x² - 48x + 144
Solving the quadratic equation at the RHS and equating it to LHS, we have:
x = 11, x = 4
Verifying the solutions by replacing the value of x with the given equation:
Therefore, we can conclude that the value of x = 4
NOTE:
Given that:
Square both sides
3x - 7 = x +5
Solve for x
3x - x = 5 + 7
2x = 12
x = 6
