Question

which of the following statements is true about dependent and independent events?
o a. if p(d | m) is not equal to p(d), then events d and m are dependent.
o b. if p(d | m) is equal to p(d), then events d and m are independent.
o c. if p(d | m) is equal to p(d), then events d and m are dependent.
o d. if p(d | m) is not equal to p(d), then events d and m are independent.

Explanation:

The definition of independent events states that if the conditional probability of event D given event M, P(D|M), is equal to the probability of event D, P(D), then events D and M are independent. If P(D|M) is not equal to P(D), the events are dependent.

Answer:

B. If P(D | M) is equal to P(D), then events D and M are independent.
