WebWhen we look at probabilities though, we see that about 10\% 10% of all people are left-handed, but about 12\% 12% of males are left-handed. So these events are not independent, since knowing a random person is a male increases the probability that they are left-handed. The big idea is that we check for independence with probabilities. WebIn this scenario, the marginal probability is not the same as the conditional probability. This means that given the student is a graduate, changes the likelihood that the student is a female. This is reflective of events that are not independent i.e. they are considered dependent events.
