could anyone help me to solve this? I am not able to think where to start this..please help and give hints Rain causes bus failure. The bus failure causes Anil and Hari to be absent.
P(Anil absent when bus fails)=0.3
P(Anil absent when bus does not fail)=0.2
P(Hari absent when bus fails)=0.3
P(Hari absent when bus does not fail)=0.2
P(Bus fails on a rainy day)=0.4
P(Bus fails on a non rainy day)=0.1
Today Anil is absent but Hari is present. What is evidence for rain?
