Discussion Overview

The discussion revolves around determining the probability of rain on two consecutive days, focusing on the lack of information regarding the probability of rain on a single day. Participants express confusion about the origin of the probability value (0.2) and the implications of missing data.

Discussion Character

  • Exploratory, Debate/contested, Homework-related

Main Points Raised

  • One participant questions the source of the probability value (0.2) and expresses uncertainty about its relevance.
  • Another participant agrees that the problem does not provide sufficient information about the probability of rain on a single day, suggesting that all options presented are valid squares of a probability.
  • A third participant admits to a lack of confidence in their understanding of probability and speculates about potential hidden meanings in the problem.
  • One participant emphasizes the necessity of knowing the probability of rain on one day to calculate the probability for two days, noting that the information may have been omitted or provided earlier.

Areas of Agreement / Disagreement

Participants generally agree that the problem lacks clarity regarding the probability of rain on a single day, but there is no consensus on how to proceed without that information.

Contextual Notes

The discussion highlights the dependence on the assumption that the probability of rain on one day is known, which is not explicitly stated in the problem. There is also uncertainty about whether the probability value was provided earlier in the thread.

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.
