Answer:

C. 0.25

Step-by-step explanation:

The number of calls answered = 40

The number of calls not answered = 120


\begin{gathered} \text{Total number of calls so far=120+40} \\ =160 \end{gathered}

The approximate probability that someone answers the next call he makes will be:


\begin{gathered} =\frac{\text{Number of calls answered}}{\text{Total number of calls}} \\ =(40)/(160) \\ =(1)/(4) \\ =0.25 \end{gathered}

The correct choice is C.
