If a random variable Y follows a Poisson distribution with parameter λ = 3, what is the probability that Y = 2? A. 0.2240 B. 0.1991 C. 0.2408 D. 0.1494 相关知识点: 试题来源: 解析 B。本题考查泊松分布的概率计算。泊松分布概率公式为 P(X = k) = (λ^k * e^(-λ)) / k! 。
If X is a poisson distribution such that P(X=1)=P(X=2)then,P(X=4)= View Solution A random variate X takes the values 0, 1, 2, 3 and its mean is 1.3. IfP(X=3)=2P(X=1)andP(X=2)=0.3, thenP(X=0)is equal to
