Conditional Probability, Distribution Function, Joint Distribution … 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.
