**Classifications**

Author(s): Elgin Johnston

Some probability problems can be solved by drawing a picture; this approach is sometimes called geometric probability. Other approaches can include experimentation, looking at smaller cases, looking at extreme cases, recursion, or carefully listing possibilities.
This session includes ten problems that can be explored alone or in sets, providing material for several circle sessions or the classroom.

Mathematical practices: MP1 – Make sense of problems and persevere in solving them., MP2 – Reason abstractly and quantitatively., MP3 – Construct viable arguments and critique others’ reasoning., MP4 – Model with mathematics., MP5 – Use appropriate tools strategically., MP6 – Attend to precision., MP7 – Look for and make use of structure., MP8 – Look for and express regularity in repeated reasoning.
