Question

You wanted to compare the theoretical probability to results of an experiment. You rolled 2 dice 50 times, and got a sum of 11 a total of 17 times. Calculate the experimental probability of rolling a sum of 11. Express your answer in any one of four different ways (i.e. decimal rounded to nearest tenth, whole number percentage, reduced fraction, words

Answer 1

Experimental probability of rolling a sum of 11 = Number of times sum of 11 appeared / Total number of trials

Experimental probability = 17 / 50

Experimental probability ≈ 0.34 (rounded to nearest tenth)

Or, Experimental probability = (17/50) * 100% ≈ 34%

Or, Experimental probability = 17/50

Or, Experimental probability = 17 out of 50 rolls were a sum of 11.
