Suppose we have a random variable Y, that follows a normal distribution with mean 0 and standard

deviation 1.

Please consult the statistics review and the lecture notes for more information.

For each of the following questions, find their probabilities using the z-table from this link:

Hint: Remember that the normal distribution is symmetric and adds up to 1

Hint: Remember that the table below gives Pr(Y ≤ z) where z > 0, so you might have to do

some work to get it into a state that you can use the table with.
