A direct method to obtain the joint distribution of successes, failures and patterns in enumeration problems
Let E be a pattern (single or composite) defined over a sequence of Bernoulli trials. Let X n , S n and F n be the number of occurrences of E , the number of successes and the number of failures in n trials, respectively. Also let T r , S T r and F T r be the waiting time for the rth occurrence of E...

| Shrnutí: | Let
E
be a pattern (single or composite) defined over a sequence of Bernoulli trials. Let
X
n
,
S
n
and
F
n
be the number of occurrences of
E
, the number of successes and the number of failures in
n trials, respectively. Also let
T
r
,
S
T
r
and
F
T
r
be the waiting time for the
rth occurrence of
E
in an infinite sequence of trials, the number of successes and the number of failures observed at that time, respectively. In this article we present some simple results revealing that, if we know either the distribution of
X
n
or the distribution of
T
r
we can instantly derive the joint distribution of
(
X
n
,
S
n
,
F
n
)
and
(
T
r
,
S
T
r
,
F
T
r
)
