The "totals" of each row appear at the right, and the ... May 12, 2019 · To find the probability that the respondent is male, we can simply divide the number of males who like football the most by the total number of respondents who like football the most: Thus, the probability that a survey respondent is male, given that the respondent likes football the most is 0.606, or 60.6%. As you move through the list, the cumulative relative frequency will add up. The last value in this frequency will always be 1. Adding up the values of the previous relative frequencies will generate the cumulative frequency. Relative frequency can be used to reduce very large data sets. The result can be displayed on a chart.To find the percentage, multiply the decimal by 100 to obtain 29.4%. This means that 29.4% of the raisin boxes contain 28 raisins.
