For a Poisson distribution, the mean (μ) and the variance (σ^2) are both equal to λ. Therefore, if λ = 3.2, both the mean and variance are 3.2, making statement B correct. The standard deviation (σ) is the square root of the variance, so the standard deviation is the square root of 3.2, which is approximately 1.79, making statement C correct as well.
