Exam update from zoom:

In exercis 6, there is a typo in Sigma2_inv. Since Sigma2 is [1 0; 0 1] Sigma2_inv will also be [1 0; 0 1]

Compute the probability that your sample x belongs to class 1 and class 2, p(x|=1) and p(x|=2).  Here we actually ask for p(w1|x) orally and p(x|w1) mathematically. Answer any of these questions and you will get full score. But note that you should compute it for both classes.
