Answer 1

Part A:

- The probability of rain on Monday is 50%, while the probability of rain on Tuesday is 30%. This means there is a higher chance of rain on Monday compared to Tuesday.
- The probability of rain on Tuesday is 30%, while the probability of rain on Wednesday is 40%. This means there is a lower chance of rain on Tuesday compared to Wednesday.
- The probability of rain on Wednesday is 40%, while the probability of rain on Thursday is 80%. This means there is a lower chance of rain on Wednesday compared to Thursday.
- The probability of rain on Thursday is 80%, while the probability of rain on Friday is 20%. This means there is a higher chance of rain on Thursday compared to Friday.

Part B:

Based on the weather predictions, the best day to host the outdoor cookout with family and friends would be Friday as it has the lowest chance of rain at 20%. This would provide a higher chance of having good weather for the event compared to the other days listed in the table.
