a number cube is rolled many times with the results shown in the table below.

number rolled
1 2 3 4 5 6

number of rolls
13 12 12 14 11 18

the theoretical and experiment probabilities for rolling a 2 are [close together, the same, not close together].

Theoretically, the probability of rolling a 2 is 1/6 (0.1666), in this it was 12/80, which simplifies to: 3/20, or 0.15. The practical result was very close to the theoretical probability, they are close together.

Experiment probability=(number of observed event)/(total number of observations)  in this case

P(2)=12/80=3/20  (≈15%)

Probability=(number of specific outcomes)/(total number of possible outcomes)

P(2)=1/6  (≈16 2/3%)

"Close" is subjective.  I'd say they were relatively close given that there were only 80 trials.

Set square i think so
