Part 2: The probability that drivers are using their mobile phones while driving is 20%. What is the probability that out of 15 randomly selected drivers: (i) Exactly two will be using their mobile phones? (ii) At most one will be using their mobile phones? (iii) At least one will be using their mobile phone? (iv) If 1500 cars pass a camera, how many drivers would you expect to be using their mobile phones and what would be the standard deviation.
