+We introduced a \textit{Noisy OR} to represent the causal independence of
+\textit{Burglar} and \textit{Earthquake} on Alarm. Probabilities for the causes
+of the alarm are calculated using days, in practice this means that the
+smallest discrete time interval is one day. The calculation for the probability
+of a burglar is then calculated with the following formula(taking leap years
+into account and assuming a standard gregorian calendar).
+$$\frac{1}{365 + 0.25 - 0.01 - 0.0025}=\frac{1}{365.2425}$$
+
+This gives the following probability distributions\\
