A million games took place in rainy Derby and a million games took place in sunny Nottingham." (a) Partition the sample space of 2000200 football match results' into four appropriately chosen sets B1, B2, B3, B4, clearly defining each set. (b) Constructing an annotated 2 by 2 grid, or otherwise, list the four entries of the form (P(B), P(Derby wins B;)) for each value 1< i< 4. Invent any reasonable values for each piece of information missing from the newspaper extract, (if any missing information exists). (c) Calculate P(Derby wins). (d) Calculate P(Derby wins | it rains). (e) Calculate P(Derby wins it is sunny). (f) Calculate P(it rains Derby loses). (g) Does rainy weather favour Team Derby?
