SUMMARY

The discussion centers on calculating the probability of rain over two days, specifically requiring the probability of rain on a single day, which is stated as 0.2. Participants express confusion regarding the absence of this key probability value in the problem statement. It is concluded that without knowing the probability of rain on one day, determining the probability for both days is impossible. The consensus is that the missing information is critical for accurate calculations.

ok I still don't know where the (0.2) comes from

Hmm, yes you're right from this alone we don't seem to be given the P(rain) on one day. All the choices are valid squares of a probability so I don't see some other "trick" that could be used to exclude choices. I'm with you, ksrush.
 
well I'm very weak at probability and statistics so thot there was some hidden message 🐮
 
In order to calculate the probability of rain on two days. you have to know the probability of rain on anyone day! Either they failed to mention that the probability of rain on anyone day was 0.2 or that information was given earlier.
