From the data given, discrete probability distribution as :
| x | Frequency f | Px=fn | x×Px |
| 0 | 4 | 0.20 | 0.0000 |
| 2 | 4 | 0.20 | 0.4000 |
| 3 | 6 | 0.30 | 0.9000 |
| 4 | 3 | 0.15 | 0.6000 |
| 6 | 1 | 0.05 | 0.3000 |
| 8 | 2 | 0.10 | 0.8000 |
| Total | n=20 | 1 | 3 |
From the data given in the table,
∑x×Px=3μ=3
Thus, the mean is 3

Students will ask 20 classmates and/or strand mates random question that will
require 1 quantitative discrete answer. They will then evaluate the answers and find its
corresponding probability. The students will solve and interpret the mean, variance and
standard deviation of the obtained data.
