    according to ur diagram...buying hardcover has a prob of .35 but buying a paperback has a prob of .65...here .65>.35 therefore prob for buying paperback is more than prob of buying hardcover.. this directly means the first option...

    let them be....but the probabilities are given to us....basically...forget this independency and all that stuff....basically prob is the chance for anything to happe...if it is high it simply means that there is higher chance for that event to take place....
