Often the main experiment consist of a sequence of sub-experiments, each depending
on the outcome of the previous one. If n such sub-experiments are chained, then
the full experiment results in a chain of events, or a path 
. If we assume that k-th experiment depends on the outcome
of the k-1-th experiment only, then 
.
Denoting by 
the generic path 
, and by
we have the following path integral formula for the
probability of an event 
specifying the outcome of the complete
experiment, and consisting of many paths .
