why is it 96%? I also got 81.5%
the question said at least one of them earns b/w 15 and 30, so you had to find the prob of both of them not earning b/w that (ie 0.185 x 0.185) and then do 1 - (0.185 x 0.185)

Question 8 for all intents and purposes is literally the exact same as Question 9 of the 2016 Ext 1 HSC...

Why would the exam committee recycle stuff like this? Seriously what's the point?
