just a few things to comment on

• in the statement equation it says 'expected of times' which doesn't make sense
• maybe you could explain what p(film) is somewhere
• the way you have phrased '120 people buy tickets to see one of...' makes it sound like they all bought the same film ticket
• i think you can omit 'by rolling a 2 or 4' in b i as you say it twice
• in your advice for b ii you could maybe state the frequncy of outcome a bit clearer and after the equation
• maybe in your advice you could adapt it when the fraction can't be simplified to simply say it is in it's simplest form
• in advice for the last part you can omit 'using the experimental data' as you say it twice

question looks good, just a few little things

• question b only has one part so i is unnecessary (same in advice)
• advice for parts a, c and d when you do your subtraction make sure it is clear that you are subtracting the whole equation as it looks like you are just making your left hand side negative at the moment
• text on advice for a iv is centred whereas the rest of the advice isn't 
• text for the advice of part c is centred too
• part c advice needs a full stop after x= recurring number, before 'By multiplying...'
• for your advice for part c maybe include the fact that you are doing the subtraction to remove the recurring numbers
• the line beginning 'From this...' continues off the page so can not be read, perhaps because it is in LaTeX 
• I'd put a space between your final fraction and 'in it's fractional form
