The total number of days for which the record is available = 250
(i) P(the forecast was correct on a given day)
Number of days when the forecast was correct / Total number of days for which the record is available = 175/250=0.7
(ii) The number of days when the forecast was not correct = 250 - 175 = 75
So, P(the forecast was not correct on a given day)=75/250=0.3
