Question

Kirk's grandparents are really enjoying their portable music players and have downloaded many more albums. Maude now has 225 albums, 135 of which are heavy metal. Claude now has 420 albums, 270 of which are heavy metal. Which of Kirk's grandparents has a higher probability of listening to heavy metal?

Answer 1

To find who has a higher probability, we need to find the percentage of each grandparent's music that is metal.

Maude:
135/225 = 0.6 = 60%

Claude:
270/420 = 0.64 = 64%

Assuming each album has the same number of tracks, Claude has a higher probability of listening to heavy metal.
