Variants of δ-normality and δ-normal separation called weakly (functionally) δ-normal spaces are introduced and studied. This
yields new factorizations of normality and δ-normality. A Urysohn type lemma and a Tietze type extension theorem for (weakly)
functionally δ-normal spaces are obtained.
In  Kohli and Vashistha gave an analogue of probabilistic version of Pant‘s Theorem (, Theorem 1). We note that mappings defined in Examples 3.6 to 3.8 of  are not self maps as claimed in the Definitions 3.1 and 3.2. In this context, we provide some relevant examples to complete the interesting results.
