Dear Sir,
I have been studying Example 1 in Chapter 23 of the September-December 2019 MA notes , and I don't quite understand why the answer of (c) is 55/150? I think it should be (40+50)/150, since the question asks the probability of a wage larger than 2000. Could you please help me with it?
Besides, I would like to know when will the videos for Chapter 22 and Chapter 23 be released? Because these two chapters seem to be the new chapters in the September-December 2019 MA notes.
Sincere thanks!

A Question in September-December 2019 MA notes
7y ago#1The new lectures will be on the website shortly, and I will work through and explain the example in the lectures :-)
7y ago#2I checked the answers and you are correct - the answer to part (c) of example 1 should read 90/150 = 0.60.
Thanks :-)
I will have the page corrected.
