Answer:
So, the argument is strong.
Step-by-step explanation:
From exercise we have that:
If a very reliable weather person argues for rain tomorrow on the basis of a 60% chance.
So the remaining 40% is that the rain does not fall, which means the day is sunny.
As 60% is more than 40%, we conclude that this is a strong argument for tomorrow's rain.
So, the argument is strong.
