Question 16
Chen writes a computer program to display one of these numbers on a screen.
1 2 3 4
Chen runs the program 1000 times.
The frequency table shows the number of times the program displays each number.
| number | frequency |
|:---:|:---:|
| 1 | 12 |
| 2 | 497 |
| 3 | 88 |
| 4 | 403 |
Chen says,
'The probability that my program displays an odd number is the same as the probability that it displays an even number.'
The data suggests that Chen is **not** correct.
Explain how Chen's data shows this.
