Each of 12 refrigerators of a certain type have been returned to a distributor because of the presence of a high pitched oscillating noise when the fridge is running. suppose that 5 of these 12 have defective compressors and the other 7 have less serious problems. if they are examined in a random order, let x= the number among the first 6 examined that have a defective compressor. compute the following

a) p(x=5)

b) the probability that x exceeds its mean by more than 1 standard deviation

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
