Question

Which statement is true about whether Z and B are

Answer 1

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.

Answer 2

Answer:

The correct answer is:

A. Z and B are independent events because P(Z∣B) = P(Z).
