ANSWER

Option D


(235)/(998);0.235

Step-by-step explanation

Given:

Total number of investors = 998

Number of investors tracking daily stock = 235

Determine the probability


\begin{gathered} Prob=\frac{number\text{ of investors tracking daily stock}}{total\text{ number of investors}} \\ =(235)/(998) \\ =0.235 \end{gathered}
