To get the cumulative relative frequency of 20 grams of sugar, we divide that number by the total number of drinks, namely 32. From the graph, we see that the cumulative relative frequency of 20 grams of sugar is approximately 0.3, which means that about 30% of the 32 drinks contained at most 20 grams of sugar. Then the probability is approximated by finding the relative frequency. \[P(A) = \dfrac{\text{Number of ways A occurred}}{\text{Number of times the experiment was repeated}}\] Important: The probability of any event A satisfies 0 ≤ P(A) ≤ 1, keep this in mind if the question is asking for a probability, and make sure your answer is a number …Suppose I want to calculate the proportion of different values within each group.
