Quizplus · Accepted Answer

The probability of fewer than six tickets being written, when the number of tickets follows a Poisson distribution with a mean (λ) of 9.2, can be calculated using the Poisson probability formula. The correct answer involves calculating the sum of probabilities for 0, 1, 2, 3, 4, and 5 tickets, which results in approximately 0.104074.
