Step-by-step explanation:
Sample space is attached below :
Theoretical Probability of any event A
P(A) = (number of required outcome / Total number of possible outcomes)
Required outcome = sum greater than 7 = 14
Total number of possible outcomes = 32
P(sum greater than 7) = 14 / 32
P(sum greater than 7) = 7 / 16

This conclusion can be drawn from the below observations
- The graph is not defined at x = 0 so y is inversely proportional to x
- The graph tends to zero as x tend to infinity which happens when y is inversely proportional to x
- The graph is symmetric about the origin so the exponent of x in the denominator should be an odd number
