btw question 20b is 4/15 but good video

[kieranoreilly]

for question 25b could you please explain how you knew what to calculate for because the question asks to find the probability of there being at least 2 red balls but from your tree diagram wouldn't there always be at least 2 red balls remaining

hi Q10, there is enough paint. 168/7=24 24x4=96L 24x3=72 its 168L. Is it correct?

On Q10, what was the purpose of multiplying by 28 rather than 24? I’m confused.
