WebGiven histamine is endogenous in the human body, low doses are unlikely to be toxic. It is when individuals are exposed to histamine levels at doses in excess of their individual tolerance that histamine may become toxic. Excess histamine can effect the cardiovascular system (tachycardia, headache, hypotension, rash and WebIn Poisson distribution, the mean of the distribution is represented by λ and e is constant, which is approximately equal to 2.71828. Then, the Poisson probability is: P (x, λ ) = (e– λ λx)/x! In Poisson distribution, the mean is represented as E (X) = λ. For a Poisson Distribution, the mean and the variance are equal. It means that E (X ... byu ip\u0026t
