A and B are independent events.<br><br> P(A) = 0.40<br> P(B) = 0.30<br><br> What is P(A/B)
Lelechka [254]

Answer: Hello mate!

Two independent events, mean that the fact that, if the event A occurred, this has no effect in the probability of the event B to occur after.

For example, a coin flip.

The first result has no effect on the next result.

Then the notation P(A/B)  is the probability of the event A when the event B occurred before, but as we know, the fact that the event B occurred before has no effect in it; so:

P(A/B) = P(A) = 0.30
