I didn't understand...please help

To find the chances that Susie would be cooking on the night her Aunt Nancy stops by randomly, we need to determine the total number of possible nights Aunt Nancy can visit and the number of nights Susie cooks.

Susie washes dishes three nights a week, washes clothes one night, empties trash cans two nights, and cooks supper one night. So, she is involved in activities for a total of 3 + 1 + 2 + 1 = 7 nights.

In a week, there are 7 nights in total. Therefore, the chances of Aunt Nancy stopping by on a night when Susie is cooking can be calculated by dividing the number of nights Susie cooks by the total number of nights in a week:

Chances = (Number of nights Susie cooks) / (Total number of nights in a week)

Chances = 1 (the number of nights Susie cooks) / 7 (total number of nights in a week)

Therefore, the chances that Susie would be cooking on the night her Aunt Nancy stops by randomly is 1/7 or approximately 0.142857.

So, there is about a 14.29% chance that Susie would be cooking on the night her Aunt Nancy stops by randomly.
