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

Maude - 225 albums, 135 heavy metal, 135/225 = 0.6 = probability of listening to heavy metal

Claude - 420 albums, 270 heavy metal, 270/420 = 0.64 (2 DP) = probability of listening to heavy metal

Assuming the albums are picked randomly ... Claude has the highest probability of listening to heavy metal at 0.64 (2 DP), appose to Maude whose probability is less at 0.6.
