In class total nmber of students is n(T) = 38.

The number of students with three or more than three siblings are


\begin{gathered} n(\ge3)=3+1+0+1 \\ =5 \end{gathered}

Determine the probability for the students with three or more than three siblings.


\begin{gathered} P(\ge3)=(n(\ge3))/(n(T)) \\ =(5)/(38) \\ =0.13157 \\ \approx0.132 \end{gathered}

Thus answer is 5/38 or 0.132.
