(ct) The Posson distribution is deployed by engineers for extreme events. If events happen independently af each other, with average number of events in same fixed interval 1, then the distribution of the number of events k in that interval is Poisson and takes the form : e-dak P(X = k) = k! (i) European railway statistics compiled by mechanical engineers over the past 50 years reveal that 4 train crashes cccur on average in continental europe and the UK each year. Assuming the data follows a Poisson distribution, evaluate the probability that there will be 2 crashes this year.

The warld database for theme parks indicates that 5 serious rollercoaster
incidents arise globally on average, worldwide (i.e. multiple deaths in any
single incident). Mechanical engineers desire to know the probability that in
2021 there will be 3 incidents. Use Poisson's distribution to compute the
probability.
