Suppose a large # of students are surveyed about how they travel, $G - 0.5$, $B - 0.4$, $W = 0.8$
Given that: $W$ is independent of $G$ and $W$ is independent of $B$, but $B$ is mutually exclusive of $G$, what is the probability that a random student does none of them?
We want $P(\overline{W} \cap \overline{G} \cap \overline{B})$, but how can I split it?
