Question

A weather forecasting website indicated that there was a 60​% chance of rain in a certain region. Based on that​ report, which of the following is the most reasonable​ interpretation? Choose the correct answer below.

A. 60​% of the region will get rain today.
B. In the​ region, it will rain for 60​% of the day.
C. There is a 0.60 probability that it will rain somewhere in the region at some point during the day.
D. None of the above interpretations are reasonable.

Answer 1

C. There is a 0.60 probability that it will rain somewhere in the region at some point during the day.

Explanation:

The probability that it will rain is given by =p= 60% = 0.6

60​% chance of rain in a certain region means that the probability of rain in the given region is 0.6 at any time of the day in any part of the region.

So Choice C is the best option.

Choice A is wrong because 60% of the region does not mean 60% of the rain.

Choice B is also wrong because 60​% of the day does not mean 60% of the rain.

The weather report tells about the rain , not the region or part of the day. So choice C is the best option
