Question

Kirk is helping his grandparents set up their new portable music players. His grandmother, Maude, has 1 jazz album, 2 country-western albums, and 5 heavy metal albums. Kirk's grandfather, Claude, has 3 classical music albums, 2 rap albums, and 7 heavy metal albums.

If Kirk's grandparents' portable music players are on random shuffle mode, who has the greater chance of listening to a heavy metal album? Explain how you know.

Answer 1

Answer: Grandma

Explanation:

His grandmother because the chance a heavy metal album comes on is 5 times out of 8 while his grandfather is 7 times out of 12. For a better representation grandma is 15/24 while grandpa is 14/24.

Answer 2

Maude

Explanation:

Maude's collection has 5 heavy metal out of a total of 8 albums

Claude's collection has 7 heavy metal out of a total of 12 albums

if you divide 5 by 8 you get .625, which is the same as 62.5%

if you divide 7 by 12 you get .583, which is the same as 58.3%

62.5% is greater than 58.3%
