Conditional probability is the probability of some event A, given the occurrence of some other event B. Conditional probability is written P(A|B), and is read 'the probability of A, given B'.

It is calculated as,

P(AB)
P(A|B) = --------
P(B)

P(AB) is the probability of the intersection of the events.

Syntax: function x = pcond(a,b,c)

Inputs:
a - Event A data vector (option=1) or probability of event A (option~=1)
b - Event B data vector (option=1) or probability of event B (option~=1)
c - Option 1=data vectors (default), option ~1=probability values

Outputs:
- Ask you if you are interested to know if the events(sets) are independent or not
- Conditional probability
