PUNCHLINE Problem Solving • 2nd Edition
 
 
PPS_136
     
  This is Part A of a two-part puzzle for partners. Students work together on essentially the same exercises but with different numbers (and answers). They are asked to discriminate between a probability and its meaning in terms of expected outcomes. Each partner gets half of the punchline.
