If the forecast area is 7000
square miles and the forecast is for a 30%
chance of rain, how much area should receive rain?
To find how much area should receive rain, we need to multiply the forecast area by the probability of rain expressed as a decimal.
30% as a decimal is 0.3.
So, the area that should receive rain is:
0.3 x 7000 = 2100 square miles
Therefore, about 2100 square miles should receive rain according to the given information.
