All the given options are correct.
what is random?
The lack of pattern or predictability in events, whether it be apparent or real, is referred to as randomness. Sometimes there is no order or discernible pattern or combination in a random series of events, symbols, or processes.
a)Random uncertainty present in the network may exhibit cumulative interactions reflecting the inherent randomness of independent activities within the network.
b)An activity having only a relative small amount of slack could potentially exceed the critical time calculated from the expected critical path.
c)As statistical variances rise in relation to expected duration, the range of uncertainty in near-critical paths will exhibit wider dispersion.
Hence all the given options are correct.

Complete Question
Why is it important to evaluate non-critical paths that possess large variances or path times that are close to critical in duration?
A) Random uncertainty present in the network may exhibit cumulative interactions reflecting the inherent randomness of independent activities within the network.
B) An activity having only a relative small amount of slack could potentially exceed the critical time calculated from the expected critical path.
C) As statistical variances rise in relation to expected duration, the range of uncertainty in near critical paths will exhibit wider dispersion.
D) All of the above.
