Meg rolled a fair six-sided die 28 times. The table below shows the number of times each number was rolled: Number Cube Experiment Number on the Cube Number of Times Appeared 1 2 2 7 3 9 4 4 5 6 6 0 According to the results in the chart, what is the experimental probability of getting a number less than 3 on the die? 19 over 28 9 over 28 7 over 28 2 over 28

So what do i do can you explain please
DanJS
  • DanJS
add up the total times he actually rolled less than 3, and divide that by his total number of rolls
DanJS
  • DanJS
(7 + 2) / 28
DanJS

That is the experimental/empirical/"real world" probability

just simplify the fraction, 9 out of 28 rolls he hit a 1 or 2
DanJS
  • DanJS
\[\frac{ total ~ 1 ~or~2}{ total~rolls }=\frac{ 2+7 }{ 2+7+9+4+6+0 } = \frac{ 9 }{ 28 }\]
