Question
Three coins were tossed 30 times. Each time the number of head occurring was noted down
as follows:
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
Solution
By observing the data given above following frequency distribution table can be constructed
| Number of heads | Number of times (frequency) |
| 0 | 6 |
| 1 | 10 |
| 2 | 9 |
| 3 | 5 |
| Total | 30 |
