As you can see in the picture, I am adding index entries to my thesis. However, there are some main entries, like probability or random, are not defined or discussed separately. Only the sub-entries probability density function, probability measure, and probability space are defined. The same are true for random element and random variable. I think it is not good to have page numbers after the main entries, which are not defined. Is there a way to remove page number for such entries?

You just don't have to add \index{probability}:

\documentclass{book}
\usepackage{imakeidx}

\makeindex

\begin{document}

\setcounter{page}{42}

a\index{probability!space}\index{probability!measure}

\clearpage
\setcounter{page}{44}

b\index{random!element}\index{random!value}

\clearpage

c\index{probability!density function}

\printindex

\end{document}
