(a) Consider a group of four students. Each student has a favourite colour, which can be any one of the colours of the rainbow (red, orange, yellow, green, blue, indigo, violet), assuming that each colour is equally likely as a favourite colour. What is the probability that no two students have the same favourite colour? (b) Consider a group of seven students. Each student has a favourite colour, which can be any one of the seven colours of the rainbow (assuming again that each colour is equally likely as a favourite color). i. What is the probability that no two students have the same favourite colour? ii. What is the probability that some of them have the same favourite colour?
