When a computer disk manufacturer tests a disk, it writes to the disk and then tests it using a certifier. The certifier counts the number of missing pulses or errors. The number of errors in a test area on a disk has a Poisson distribution with $\lambda = 0.2$ .

What percentage of test areas have two or fewer errors?

96.89% 97.89% 98.89% 99.89%

But answer is 96.89, please correct it. I checked 99.89 and it shows "Incorrect".

99.89 is correct when x=0 and x=1 and x-2 using lambda=0.2
