Three experiments are conducted in which a single 6 sided die is rolled 15, 30, and 45 times. The outcomes of the experiments are shown here. For each result calculate the experimental probability of rolling a 4. Express your answer as a reduced fraction and a decimal rounded to three decimal places.

Experiment 1: 15 rolls

Experiment 2: 30 Rolls

Experiment 3: 45 rolls
