Answer:
Part A: Comparing the probability of rain between any two days, we can observe the following:
- Monday (83%) vs. Tuesday (65%): The chance of rain is higher on Monday (83%) compared to Tuesday (65%).
- Tuesday (65%) vs. Wednesday (35%): The chance of rain is higher on Tuesday (65%) compared to Wednesday (35%).
- Wednesday (35%) vs. Thursday (48%): The chance of rain is higher on Thursday (48%) compared to Wednesday (35%).
- Thursday (48%) vs. Friday (10%): The chance of rain is higher on Thursday (48%) compared to Friday (10%).
Part B: Based on the weather probabilities provided, the best day to host the outdoor cookout would be Friday with a 10% chance of rain. Among the five days, Friday has the lowest probability of rain. This means it is less likely to experience rainfall, making it a favorable choice for an outdoor event.
However, it's worth noting that weather forecasts are not always completely accurate, and there is still a small chance of rain on Friday. It would still be a good idea to have a backup plan or be prepared for unexpected changes in the weather.
