Answer:

Z and B are independent events because P(Z I B) = P(Z)

Step-by-step explanation:

  • If Z and B are independent, Z does not affect B and B does not affect Z.
  • This means that, to know something about B does not help predicting Z, and to know something about B does not help predicting Z.
  • Then,  the probability P (Z/B) = P(Z) because B does not add any information about Z, therefore, the probability of Z only depends on itself.
