Following the lock-down in the UK due to Covid-19, some adults were suffering greatly from the isolation they had endured. The prospects of graduating with a decent degree and finding jobs in the future were concerns affecting a lot of young adults. John and Jane (JJ) are two young adults who were trying to work out the chances (probabilities) of events occurring based on historical information. They were both looking at various aspect of the near future job market. c) Jane suggests that they try throwing a fair coin. Joh says what about using a coin with two heads.

Use Bayes' theorem to work out the posterior probability that the coin is fair. (30 marks) CUT
