Which equation implies that a and b are independent events? a. b. c. d. e.
tiny-mole [99]

Using conditional probability, the equation that implies that a and b are independent events is P(B|A) = P(B).

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which:

  • P(B|A) is the probability of event B happening, given that A happened.
  • P(A \cap B) is the probability of both A and B happening.
  • P(A) is the probability of A happening.

If A and B are independent events, we have that:

P(A \cap B) = P(A)P(B).

Then, at the conditional formula:

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)P(B)}{P(A)} = P(B)
