Within a month after the restoration of the asphalt pavement, on average, there is one
significant defect for every 2 kilometres. Generate a Poisson probability distribution
for the random variable ‘the number of significant defects in a 10 km section one
month after the asphalt change’. Find the probability of these events:
(a) there are no significant defects in a given 10 km section;
(b) there is at least one significant defect in a given 10 km section.
