1. A study was done of the number of cardiac arrests to occur per week in a particular hospital of 850 beds over a period of 5 years. The number of cardiac arrests fulfills the requirements for the Poisson probability distribution and has a mean of μ=1.09 cardiac arrests per week. Calculate the following probabilities:

  1. The probability of two cardiac arrests in a given week
  2. The probability of fewer than two cardiac arrests in a week
  3. The probability of at most two cardiac arrests in a week
  4. The probability of more than two cardiac arrests in a week
  5. The probability of at least three cardiac arrests in a week
