Probabilità condizionata?

Ciao gente, non riesco a capire il perchè di un'operazione.
Esercizio DITTATORE, capitolo 4.a dell'eserciziario della prof.

Dichiara X bernoulliana di parametro p e M bernulliana di parametro mu. Y = X+M(1-X)

In un esercizio chiede: P(Y=1|X=0).

La soluzione è P(1=0+M*1) dunque P(M=1)=mu: a logica direi che ci credo, ma teoremi alla mano non mi quadra...

Infatti da definizione P(A|B) = P(A intersecato B)/P(B) ed in questo caso avrei P(condizionata)=P(1=0+M*1)/P(X=0), ovvero otterrei mu/(1-p)...

Dove sbaglio??? :? :(
