Answer 2

Answer:

PoP = C x A where "C" = the confidence that precipitation will occur somewhere in the forecast area, and where "A" = the percent of the area that will receive measurable precipitation, if it occurs at all. But, most of the time, the forecaster is expressing a combination of degree of confidence and areal coverage

Step-by-step explanation:

Let A denote the events that it rains today and B denote the event that it will rain tomorrow. Then it is given that P(A) = 40/100 = 2/5 and P(B) = 45/100 and P(A·B) = 20/100 = 1/5 . Now the required probability = P(B/A) = P(A·B)/P(A) = (1/5)/(2/5) = 1/2 .

you can do by using this method
