I made a mock exam to match 2020. Use as you’d like. There are solutions and a few teacher notes. Enjoy.
Thanks to my friend Jeff for editing help!
Edit: The answer to #2e is incorrect. It should be (56/75)^4. Sorry about that!
Edit 2: NOPE! #2e is 1 - (19/75)^4 = 99.6%. Thanks Steve! So sorry everyone!
