The number of two wheelers owned individually by each of 50 families are listed below. Make a table using tally marks.

1, 1, 2, 1, 1, 1, 2, 1, 2, 1, 0, 1, 1, 2, 3, 1, 2, 1, 1, 2, 1, 2, 3, 1, 0, 2, 1, 0, 2, 1, 2, 1, 2, 1, 1, 4, 1, 3, 1, 1, 2, 1, 1, 1, 1, 2, 3, 2, 1, 1

Find the number of families having two or more, two wheelers.

Answer 1

Number of two wheelers	Tally marks	Number of families
0	`bb|bb|bb|`	3
1	`cancel(bb|bb|bb|bb|)` `cancel(bb|bb|bb|bb|)` `cancel(bb|bb|bb|bb|)` `cancel(bb|bb|bb|bb|)` `cancel(bb|bb|bb|bb|) bb|bb|bb|`	28
2	`cancel(bb|bb|bb|bb|)` `cancel(bb|bb|bb|bb|) bb|bb|bb|bb|`	14
3	`bb|bb|bb|bb|`	4
4	`bb|`	1
Total		50

So, 14 + 4 + 1 = 19 families have two or more, two wheelers.
