Conditioned
Conditioned
or
represents
expr
conditioned by the predicate
cond
.
MORE INFORMATION
can be entered as

cond
or
.
The expression
expr
can correspond either to a predicate with logical values or to an object with numerical values.
Probability
gives the conditional probability of
pred
given
cond
.
Expectation
gives the conditional expectation of
expr
given
cond
.
Conditioned
can be used in functions such as
Probability
,
NProbability
,
Expectation
, and
NExpectation
.

Properties & Relations
(3)
A conditional probability is a ratio of two probabilities:
The conditional probability is 0 if the events are mutually exclusive:
Compute the probability of an event in a
TruncatedDistribution
:
Obtain the same result using a conditional probability calculation:
Possible Issues
(1)
Conditioned
has lower precedence than
And
:
Use parentheses to obtain the intended result:
