The number of persons joining a cinema ticket counter in a minute follows a Poisson distribution with parameter 6, then the probability that at least one and at most five persons join the queue in a particular minute is
- A \(\mathrm{e}^{-6 \times 6}(25.48)\)
- B \(e^{-6}\left(\frac{6}{2}+\frac{6^3}{3 !}+\frac{6^4}{4 !}\right)\)
- C \(6 \times \mathrm{e}^{-6}(29.8)\)
- D \(e^{-6}\left(6+\frac{6^2}{2}+\frac{6^3}{3 !}+\frac{6^4}{4 !}\right)\)
