Shurley bought a new bed and now needs to find pillows, sheets, and a comforter for it. she wants to have black and white pillows; striped or plaid sheets; and a solid, polka-dot, or zebra print comforter.

How many unique bedding combinations can Shurley make?

12

Step-by-step explanation:

The fundamental counting principle states that to find the total number of combinations, we multiply the choices for each element.

She can choose between 2 types of pillows; 2 types of sheets; and 3 types of comforters.  This gives us

2(2)(3) = 4(3) = 12
