What are you trying to prove here? I know when step will be the use of the Transitive Property. If a=b, and b=c, then a=c.

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:

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

5*4*3*2*1

We can cancel out the 5*4*3*2*1 to give:

9*8*7*6
