00:01 Alright, so here the question says that there are two events a and b which are independent and the probability of event a is given as 0 .25.
00:10 Now here we have been asked that what will be the probability of event a given b.
00:15 Right, now if a and b are independent events then the probability of a given b is equal to either the probability of a and the probability, sorry, this is equal to the probability of a and if the probability of b given a is equal to the probability of event b.
00:36 Right, so for the given scenario we need to determine the probability of a given b...
