CPM Homework Help : CCAA Problem 8-64

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 $450$ albums, $270$ of which are heavy metal. Which of Kirk’s grandparents has a higher probability of listening to heavy metal?

Step 1:

Find the probability each grandparent has of listening to heavy metal.

Maude: $\frac{135\text{ metal}}{225\text{ total}}=\frac{3}{5}$

Claude: $\frac{270\text{ metal}}{450\text{ total}}=\frac{3}{5}$

Answer:

They have the same probability of listening to heavy metal.
