If we have two events from the same sample space, does the information
about the occurrence of one of the events affect the probability of the other event Let
us try to answer this question by taking up a random experiment in which the outcomes
are equally likely to occur Consider the experiment of tossing three fair coins The sample space of the
experiment is
S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}

Since the coins are fair, we can assign the probability  1
