Given:

Total number of students: T = 147

Number of students taking math : M = 95

Number of students taking science : S = 73

Number of students taking both math and science = 52

To find:

The theoretical probability of randomly choosing a student who is taking math.

Solution:

It is given that,

Total number of students (T) = 147

Number of students taking math (M) = 95

So, he theoretical probability of randomly choosing a student who is taking math is:


P(M)=\frac{\text{Number of students taking math}}{\text{Total number of students}}* 100\%


P(M)=(95)/(147)* 100\%


P(M)=64.62585\%


P(M)\approx 64.6\%

64.6% is the theoretical probability of randomly choosing a student who is taking math.

Hence, option C is correct.
