Continuing with our series of videos covering all the questions from the 2018 Edexcel Higher Tier GCSE Maths Paper 3, Best Maths Tutors covers question 6 and is about Probability. Here we are asked to look at a table of probabilities and work out the final two probabilities after having been told their ratio. From here we then have to work out how many red counters there are, given the number of blue counters and their relative probabilities.
