Question

Emma claims: Tomorrow it will either rain or not rain. The probability that it will rain is 0.5. Is she correct? Explain your answer fully.

Answer 1

Yes, there is a 50% chance it will rain. This leaves the other 50% chance to be that it will not rain. This fills up 100% of the possibilities. It is only logical that it will either rain or it won't, there is no third option.
