Stacy performed an experiment in which she rolled a six-sided die multiple times. The results are shown below. Result of Roll Frequency 1 19 2 24 3 35 4 38 5 18 6 56 Based on the results above, predict the number of times a 6 would be rolled if Stacy performs the experiment a total of 570 times.

Respuesta :

The number of time 6 appears is 56 and total frequancy observation is,

[tex]19+24+35+38+18+56=190[/tex]

The possibility for the 6 in 190 obsevations is,

[tex]P(x)=\frac{56}{190}[/tex]

The possibility for 570 observations is,

[tex]\begin{gathered} X(6)=\frac{56}{190}\times570 \\ =168 \end{gathered}[/tex]

So answer is 168.
