First, you have to change the problem to have like denominators. SO, 1/4 would change to 3/12. Then, you do 10/12-3/12. You should get 7/12.

If I had 3 pink clips and 2 blue clips, I'd have a most likely chance of picking a pink clip.
If you still don't get it, tell me again and I'll try again.

Hope this helps!
