There are two parts to the question. I had to split the screen to show everything

The quality-control inspector of a production plant will reject a batch of syringes if two or more defective syringes are found in a random sample of twelve syringes taken from the batch. Suppose the batch contains 1% defective syringes. (a) Make a histogram showing the probabilities of r = 0, 1, 2, 3, _, 11 and 12 defective syringes in a random sample of twelve syringes. (Select the correct graph.) 0.90 0.80 0.70 121 Email - MATH120 1005 Summer 2 x 0.60 X Homework Week 4 (ADA) - MATI x + 0 50.50 0.40 C A https://www.webassign.net/web/Student/Assignment-Responses/last?dep=29549058#Q7 0.30 0 1 2 3 4 5 6 7 8 9 10 11 12 0.20 0.10 O 0 1 2 3 4 5 6 7 8 9 10 11 12 0.90 0.80 O .70 0.60 0.90 0.50 0.80 0.40 0.70 0.30 0.60 0.20 0.50 0.10 0.40 OL 0.30 012 3 4 6 7 8 9 10 11 12 0.20 0.10 O 0 1 2 3 4 5 6 7 8 9 10 11 12 (b) Find # (in terms of the number of syringes).
