In the testing of probability axioms, it is possible to pass all test cases even if only enforcing the second axiom of probability. Any set containing values less than 0 and/or greater than 1 but summing to 1, e.g. [-1, 2], will obey the second axiom but not the first. This creates an edge case. It would be nice to have a set which creates this edge case in order to enforce more rigorous standards for solving the lab.

Students in the current in person described spending over an hour being confused about the difference between these two questions:

"""
a. What is the probability of throwing a 5 at least once?

First, use sample_dice to get "True" values for each time a 5 occurs.

set_5 = None

Next, make sure that you get a value True for each pair where at least one 5 was thrown.

true_5 = None
print(true_5)
"""

Further clarification about combining booleans and what was intended here is warranted.

Now let's try creating your own event space!
A teaching assistant is holding office hours so students can make appointments. She has 6 appointments scheduled today, 3 by male students, and 3 by female students.

Create a NumPy array te say way as we did this for you in the "throwing a dice twice" exercise. It will be quite a bit of typing, as your resulting NumPy array will have a shape (20,6)!

It was unclear of what you were looking for. A prompt of "How many ways can you fill the appointments" or "How many different ways can the students sign up for the appointments" would go a long way here.

see screen shot below - not sure but think you are trying to say "array as we did this for you"....
