Three coins were tossed 30 times. Each time the number of heads occuring was noted down as follow:
0 1 2 2 1 2 3 1 3 0
1 3 1 1 2 2 0 1 2 1
3 0 0 1 1 2 3 2 2 0
Prepare a frequency distribution table for the data given above.
Given:
Three coins were tossed 30 times. Each time the number of heads occuring was noted down as follow:
0 1 2 2 1 2 3 1 3 0
1 3 1 1 2 2 0 1 2 1
3 0 0 1 1 2 3 2 2 0
To do:
We have to prepare a frequency distribution table for the data given above.
Solution:
The required frequency distribution is:
Number of heads
| Tally marks | Frequency |
| 0 | |||| | | 6 |
| 1 | |||| ||||
| 10 |
| 2 | |||| ||||
| 9 |
| 3 | |||| | 5 |
| Total | | 30 |
