Jason tracked the days of the week for the last 50 times he was assigned homework.
The table has tally marks which represents the number of days with homework. There are 3 5-tally groups and 1 tally mark for Monday, 2 5-tally groups and 4 tally marks for Tuesday, 4 tally marks for Wednesday,2 5-tally groups for Thursday, and 1 5-tally group and 1 tally mark for Friday.
According to the results, what is the probability of his next homework assignment being assigned on a Monday?
A.
0.20
B.
0.28
C.
0.32
D.
0.47
To calculate the probability of his next homework assignment being assigned on a Monday, we need to find the total number of homework assignments and the number of times homework was assigned on a Monday.
The total number of homework assignments is:
3 groups of 5 tallies = 3 x 5 = 15
2 groups of 5 tallies = 2 x 5 = 10
1 group of 5 tallies = 5
1 tally mark = 1
Total = 15 + 10 + 5 + 4 + 10 + 1 = 45
The number of times homework was assigned on a Monday is 1.
Therefore, the probability of his next homework assignment being assigned on a Monday is:
1/45 = 0.022
So the answer is not one of the given options.
To find the probability of Jason's next homework assignment being assigned on a Monday, we need to determine the total number of homework assignments and the number of homework assignments on Mondays.
According to the information given, the table has tally marks for the number of days with homework. Let's count the tally marks for each day:
- Monday: 1 tally mark
- Tuesday: 4 tally marks (2 groups of 5-tally marks)
- Wednesday: 4 tally marks
- Thursday: 0 tally marks (no 5-tally groups)
- Friday: 1 tally mark (1 group of 5-tally marks)
To find the total number of homework assignments, we need to count the total number of tally marks for all days of the week:
Total tally marks = 1 + 4 + 4 + 0 + 1 = 10
Now, to find the probability of Jason's next homework assignment being assigned on a Monday, we divide the number of tally marks for Monday by the total number of tally marks:
Probability of Monday = Number of Monday tally marks / Total tally marks = 1 / 10 = 0.1
Therefore, the probability of Jason's next homework assignment being assigned on a Monday is 0.1.
However, none of the answer choices given matches the calculated probability of 0.1. Therefore, there might be an error in the information provided or the answer choices. Please recheck the problem or the answer choices.
To find the probability of Jason's next homework assignment being assigned on a Monday, we need to consider the frequency of Mondays compared to the total number of homework assignments.
From the given information, we know that there is 1 tally mark for Monday out of a total of 50 homework assignments. To find the probability, we divide the frequency of Mondays by the total number of homework assignments:
Probability = Frequency of Mondays / Total number of homework assignments
Probability = 1 / 50
Simplifying the fraction, we get:
Probability = 0.02
Therefore, the probability of Jason's next homework assignment being assigned on a Monday is 0.02.
However, none of the given answer options match this result.
