notes do a summary on the video of the main points in the vid
P(R)=Probability if selecting red card=26/52
P(F)=Probability of selecting face card=12/52
P(R|F)=Probabilty if selecting red card given face card=6/12=0.5
Here we know that we have face card(i.e. denominator variable)
P(F|R)=probabilty of selecting face card given red card,here we know we have red card
Another formula for finding conditional independence is
P(A|B)=P(A and B)/P(B)
If P(A|B)=P(A and B)/P(B) -->independent events
If P(A|B)!=P(Aand B)/P(B) --> dependent events
eg P(S)!=P(S|B) hence they are dependent events.
