Let x be a Poisson random variable with μ = 0.9. Find the probabilities for x using Table 2. (Round your answers to three decimal places.) P(1 ≤ x ≤ 4)

Let x be a random variable that possesses a binomial distribution with p=0.7 and n=7. Using The binomial formula or tables calculate the following probabilities also calculate the mean and do you need to be ation of the distribution Raw solutions to four decimal places, if necessary. P(x ≥ 4)= P(x ≤4)= P(x=6)= μ= σ=
