When a computer disk manufacturer tests a disk, it writes to the disk andthen tests it using a certifier. The certifier counts the number of missingpulses or errors. The numnber of errors on a test area on a disk has aPoisson distribution with A=0.15.(a) What is the expected numnber of errors per test area?(b) What percentage of test areas have 2 or fewer errors?Round your answers to two decimal places (e.g. 98.76).(a) The expected number of errors per testarea is(b) i% of test areas have two or fewererrors.

Givenλ=0.15Let "x" be the test areas have errors x~Poisson(λ=0.15)P(X=x)=e-λ×λxx! ; x≥0

Customers of a restaurant have been complaining about food poisoning over the past week. A health professional was called to investigate. She tested a representative sample of the eggs and reported that 24% of the sample eggs tested positive for the salmonella bacterium. If a second health professional tests 66 eggs at random, what is the probability that exactly 14 test positive for salmonella? Use a normal distribution to approximate the answer and write it as a decimal rounded to the nearest hundredth.
