A jigsaw puzzle consists of straight edged (including the four corners) and 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]
