still having problems on probability question with ratios and percents. If you surveyed 30 people (21 girls and 9 boys) and they picked differnt song genre's as their favorite. 3 out of the 21 girls picked country and 0 of the 9 boys picked country. The question is are females or males more likely to pick the country genre and by how much. I know females would be more likely but I don't understand how to say by how much. Thanks...

    Yes because 3 to 21 is more than 0 to 9.

    The ratios are:
    3 to 21 (because 3 girls out of 21 girls picked country)

    0 to 9 (because 0 people out of 9 boys picked country)
