Question 1188966: A student has committed the errors which follows the Poisson distribution
with an average rate of 1.5 errors per class.
i) What is the probability that she makes at least 3 errors during one class?
ii) What is the probability that she has committed two ‘error-free’ classes in
the two weeks?

this is e^(-1.5)*1.5^3/3!=0.1255
this issue e^(-1.5)*1.5^0/0!=0.2231 per week and square that for two weeks = 0.04979
