Each week Susie washes dishes three nights,washes clothes one night,empties trash cans two nights,and cook supper one night.If her Aunt Nancy stopped by randomly one night,what are the chances that Susie would be cooking that night??
1 night out of 7 = 1/7
To calculate the chance that Susie would be cooking on the night Aunt Nancy stopped by randomly, we need to know the total number of nights in a week. Let's assume a week has 7 nights.
Given that Susie washes dishes 3 nights, washes clothes 1 night, empties trash cans 2 nights, and cooks supper 1 night, we can add up these nights to determine how many nights she is occupied:
3 + 1 + 2 + 1 = 7
Since Aunt Nancy stopped by randomly on one of the 7 nights, the chance that Susie would be cooking that night would be 1 out of 7. Therefore, the probability is 1/7 or approximately 0.14 (14%).
To determine the chances that Susie would be cooking on the night her Aunt Nancy stops by, we need to calculate the ratio of cooking nights to total nights. Let's break down the activities mentioned in the question:
- Susie washes dishes three nights a week.
- Susie washes clothes one night a week.
- Susie empties trash cans two nights a week.
- Susie cooks supper one night a week.
To find the total number of nights, we add up the number of nights for each activity:
3 nights (washing dishes) + 1 night (washing clothes) + 2 nights (emptying trash) + 1 night (cooking) = 7 nights.
Then, we calculate the ratio of cooking nights to total nights:
1 night (cooking) รท 7 nights (total) = 1/7.
Therefore, the chances that Susie would be cooking on the night her Aunt Nancy stops by is 1 out of 7, or approximately 14.29%.
