Muniba wants to carry out her own study into the hair colour of people. She decides to set up a recruitment booth at Milton Keynes train station, which people can visit and volunteer to take part in the study. (c) Based on previous work, Muniba makes an assumption that the probability of someone having blond hair is 0.25. On Ada Lovelace day (13 October 2020) 5 people volunteered at Muniba's booth. Write down a suitable distribution for Y, where Y is the random variable representing the number of blond haired people who volunteered on Ada Lovelace day. (d) Use the distribution you stated in part (c) to calculate, to three decimal places, the probability that there were no blond haired people amongst the volunteers on Ada Lovelace day.
B) Since the hair colour of a random participant is an event which can be either blonde or some other colour, hence the random variable B which models the hair colour of a certain participant is modelled using a "Bernoulli Distribution" with parameter 1/2 (1.e., B~ Bern(1,1/2))
