(a)
To calculate: The relative frequency for a music download that was pop-rock, if 200 were regional (Mexican/Tejano), 130 were pop-rock, 45 were tropical (salsa/meringue/cumbia/bachata), and 25 were urban (reggaeton) were downloaded in 2009.
(b)
To calculate: The relative frequency for a music download that was neither tropical nor regional, if 200 were regional (Mexican/Tejano), 130 were pop-rock, 45 were tropical (salsa/meringue/cumbia/bachata), and 25 were urban (reggaeton) were downloaded in 2009.
(c)
To calculate: The relative frequency for a music download that was not regional, if 200 were regional (Mexican/Tejano), 130 were pop-rock, 45 were tropical (salsa/meringue/cumbia/bachata), and 25 were urban (reggaeton) were downloaded in 2009.
