The last question and the one about walking to work were the ones I struggled the most on

Same here. Last one was an X bar linear combinations although I never got it but my friend did.
Walking to work one, for the 1st I did a 27 route tree diagram and got the correct answer! The other 2 part of that question I didn't do correctly.

I feel like part 2 was bayes theorem?

What did ppl get for the last question ?

I don't remember exactly but for the last part I did T_1 - 1/4(T_1 + T_2 + T_3 + T_4) and simplified the T_1 terms down to 3/4 T_1
