the Venn diagram below models the possibility of three events a b and c the probabilities for each event or given by the ratio of the area of the event to the total area of 72 for example event C is read-only so for the probability that event C,you haveP(C)=area Red/total area =18/12×6=18/72=1/4=0.25are A&B dependent or independent events use conditional probability to support your conclusion
The events A and B are dependent events. This is because unlike the red area, event A means green given that blue has already occured. Event A includes blue and green and then event B includes green and yellow. Therefore event B cannot take place unless event A (which includes green area) has already taken place. Same goes for event A, it cannot take place unless event B has occured because the green area occurs in event B.Both events are dependent events. The result of one will influence the result of the other on.
