Question 1164190: In November, the rain in a certain valley tends to fall in storms of several days' duration. The unconditional probability of rain on any given day of the month is 0.600. But the probability of rain on a day that follows a rainy day is 0.800, and the probability of rain on a day following a nonrainy day is 0.300.
Find the probability of rain on two randomly selected consecutive days in November. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Not clear to me whether it is rain both days or rain on either of them.
the first day has rain (0.6) and the second day will have rain with probability of 0.8. That probability is 0.48--both day scenario, and what I think is the answer.
Rain-no rain: probability is 0.12
No rain-rain: probability is 0.4*0.3 or 0.12
No rain-no rain probability is 0.28
The probability there will be some rain on either or both days is 0.72.
