Question 1164190
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.
