Number of days weather was not correct = 250-175 = 75.
Probability that the weather forecast was right = 175/250 = 35/50 = 7/10 = 0.7
Probability that the weather forecast wasn't right = 75/100 = 15/50 = 0.3
Probability that the weather forecast was right = 175/250 = 35/50 = 7/10 = 0.7
Probability that the weather forecast wasn't right = 75/100 = 15/50 = 0.3
