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.
