Summing all the frequencies, we deduce the total number of trials:
[tex]4+8+36+20+12=80[/tex]
Knowing how many trials have been done, we deduce the probability of each outcome by dividing its frequency and the number of trials:
[tex]P(0)=\dfrac{4}{80}=\dfrac{1}{20},\quad P(1)=\dfrac{8}{80}=\dfrac{1}{10},\ldots[/tex]
Convert these fractions to numbers, and drag each slider where it is supposed to be.
Fox example, we have
[tex]P(0)=\dfrac{1}{20} = 0.05[/tex]
So, you'll have to drag the first slider up to 0.05, and so on.
