In a certain store, there is a 0.05 probability that the scanned price in the bar code scanner will not match the advertised price. The cashier scans 886 items.(a-1) What is the expected number of mismatches? (Round your answer to nearest whole number.)Expected number (a-2) What is the standard deviation? (Use rounded expected number for the calculation of standard deviation. Round your final answer to 4 decimal places.)Standard deviation (b) What is the probability of at least 34 mismatches? (Round the value of z to 2 decimals. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.)Probability (c) What is the probability of more than 52 mismatches? (Round the value of z to 2 decimals. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.)Probability
