Answer:
A and B are equally likely
Explanation:
The conditional probability is defined as follows:
where:
is the probability for X to occur, given that Y has occurred
is the probability that both X and Y occur at the same time
is the probability for Y to occur
Given two events A and B, we have:
and
In this problem, we are told that
Which means that:
Simplifying, we get:
which means that A and B are equally likely.
