1. A random variable X is distributed as Poisson distribution with = 3.5. Use this Poisson distribution (Table A.3) to determine the following probabilities:

1. A random variable X is distributed as Poisson distribution with λ = 3.5. Use this Poisson distribution (Table A.3) to determine the following probabilities: (a)

P(X <5),

(b) P(2 ≤ X ≤ 6),

(c) P(X >7),

(d) P(X ≥ 5).
