Thank You Internet

He said that wrong, you divide the dement

@tia0416 the division is actually a ratio. probabilities are usually calculated in ratios or percentages. for example the probability of having a sunny day out of the 5 days is 2 out of 5 hence 2/5
-

first thanks for the effort of teaching. second you got it wrong, there are THREE events here not TWO.. cloudy or sunny as you mentioned. instead we have Cloudy or sunny or cloud/sunny. thus gives
P(cloudy) = 3/5 = 0.6 = 60 %
P(sunny)= 1/5 = 20%
P(cloudy/sunny) = 100 - (P(cloudy) + P(sunny)) = 20 %
or P(cloudy/sunny) = 1/5 = 20 %
