On average, there are about 25 imperfections in 100 meters of optical cable. Assume that the number of imperfections has a Poisson distribution.

a) What is the expected number of imperfections in 500 meters of cable?

Solution

expected numbers for a poisson distribution is landha

landha in this case is 25 imperfections in 100 meters

but we need for 500 meters so that will be

25 / 100 * 500 = 125

a) What is the expected number of imperfections in 500 meters of cable?

125 imperfections in500 meters of calbe
