Conditional marginal and joint probabilities
WebWhen we look at probabilities though, we see that about 10 % 10\% 1 0 % 10, percent of all people are left-handed, but about 12 % 12\% 1 2 % 12, percent 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.
