Required
The packages less than 30 kg.
To do this, we simply add up the frequencies of packages less than 30 kg.
From the chart, we have:
[tex]x \to Frequency[/tex]
[tex]0 - 9 \to 0.55[/tex]
[tex]10 - 19 \to 0.55[/tex]
[tex]20 - 29 \to 1.90[/tex]

[tex]Total = 0.55 + 0.55 + 1.90[/tex]
[tex]Total = 3[/tex]
