Hi can someone explain to me why conditional probability must be used in part (ii). I understand that the question wants me to use conditional probability from the key word "given", but am not sure why P(X=4)+P(X=5) is not accepted. Doesn't both these probabilities fulfil the requirements (1 head and at least 4 tails)?
