A worked example

What is the probability that you pick a red marble from a bag with 2 red and 3 blue, and then spin a 4-part spinner and land on red? 1/10

  1. First event: 2/5. Second event: 1/4
  2. Independent events, so multiply: 2/5 × 1/4 = 2/20
  3. Divide top and bottom by 2: 1/10

About these worksheets

The wording stays familiar while the numbers change, which is what makes the method stick rather than the answer. Every sheet is generated fresh, so you can print a new one on the same skill as often as you need — different numbers, same difficulty.

Pick how many problems you want and whether they should be easy, medium or hard, then download a PDF with a matching answer key. The key can show the worked steps for every problem, which is what a parent needs to see where a wrong answer went wrong.
