The answer is most likely 4 but I think you need a table or a marked hygrometer to work this out. You can't really work out humidity by the given temperatures. All you can know for sure is that there is a strong chance of rain because dew point is only 1 degree away. (I think what they want you to do is 29/30 x100)
