For some reason I done my work right on this one, but i got it wrong, im not sure what i do wrong, thank you.

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 often syringes taken from the batch. Suppose the batch contains 1% defective syringes. (a) Make a histogram showing the probabilities ofr = 0, 1, 2, 3, ..., 9 and 10 defective syringes in a random sample of ten syringes. (Select the correct graph.) 1.00L 0.90 0.80 0.70- 0.60 0.50 0.40 030 0.20 0.10 0 P0) 1.00L 0.90 0.80 0.60 0.50 0.40 050- 0.20 0.10 PU) 1.00L 0.90 0.80 0.70 0.60 0.50 0.40 0.30 0.20 0.10 Hr) 1.00L 0.90 0.80 0,70 0.60 0.50 0.40 030 0.20 0.10 P(r) (b) Find )1 (in terms of the number of syringes). (Enter a number. Enter your answer to two decimal places.) )1 = 00.5 X syringes What is the expected number of defective syringes the inspector will find? (Enter a number. Enter your answer to two decimal places.) 0.5 x syringes (c) What is the probability that the batch will be accepted? (Enter a number. Round your answer to three decimal places.) 0.9138 x (d) Find a (in terms of the number of syringes). (Enter a number. Round your answer to three decimal places.) a = 0.689 x syringes
