australopithecus · Answer

The notaiton P(A|B) means the probability of A given that B has occured

australopithecus · Answer

you have to assume the events are independent

australopithecus · Answer

The question is badly worded or just off, 4 isn't a odd number, if you know you rolled an odd number the the chances of an even number is 0 unless otherwise stated

australopithecus · Answer

4 is not part of the odd number set {1,3,5}

australopithecus · Answer

Based on how the question is worded the probability is 0
