Ok I see... so its just a case of realising that its q14, there must be an easy way, and then spotting that if you pick one, then there are 4 other people out of the 5 who can speak your language, makes sense.
I really need to stack the practice up for these probability qs (and geometry yikes), but luckily my schools finally over so ill get some more time.
If you were sitting this q in the exam, would you list all the probabilties/outcomes out in a table? I always thought that was a bad idea since time, or would you do it by choosing 1 student and seeing what happens to the probabilties from there..?
