In a given city it rains 25% of the days. A meteorologist has an 80% chance of getting his forecast right for sunny days, while for rainy days this probability drops to 60%. For a randomly chosen day, find the probability that: (a) the meteorologist is correct in his forecast for that city. (b) it rains in that city, since the forecast is for rain.
