Questions

A jigsаw puzzle cоnsists оf strаight edged (including the fоur corners) аnd non-straight edged pieces.  When a jigsaw piece is randomly selected from the box, there is about a 12% chance of selecting a straight edged piece.  You take a simple random sample of 6 jigsaw pieces from the box.  Let X = the number of pieces that have a straight edge.  The distribution of X is binomial with n = 6 and p = 0.12.   a. How would you write the distribution of X using symbols? [1]   b. What is the sample space of this distribution? [2]   c. What is the probability of getting 2 or 3 straight edged pieces from the 6 randomly selected pieces? [3]
