Question

the weather table predicts the chance of rain for five days.

day of the week	chance of rain
tuesday	15%
wednesday	41%
thursday	45%
friday	68%

part a: compare the probability of rain between any two days. (2 points)
part b: based on the weather, if you are planning an outdoor cookout with family and friends, which day will be better to host the outside event? explain your answer. (2 points)

Explanation:

Part A

Step1: Choose two days (e.g., Monday and Tuesday)

Monday: 72%, Tuesday: 15%

Step2: Compare the percentages

72% > 15%, so Monday has a higher chance of rain than Tuesday. (We can also compare other pairs: e.g., Wednesday (41%) vs Thursday (45%): 41% < 45%, so Thursday has a higher chance than Wednesday; Friday (68%) vs Monday (72%): 68% < 72%, so Monday has a higher chance than Friday, etc.)

To host an outdoor cookout, we want the day with the lowest chance of rain (to minimize the risk of rain ruining the event). Looking at the table, Tuesday has a 15% chance of rain, which is the lowest among the five days. A lower chance of rain means a higher probability of good weather for the outdoor event.

Answer:

For example, comparing Monday (72%) and Tuesday (15%): The chance of rain on Monday (72%) is greater than on Tuesday (15%). (Other valid comparisons are also acceptable.)
