Lubov Fominskaja [6]

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

\to p(x\leq 2)=p(0)+p(1)+p(2)

                  =e^{-2.2}(1+2.2^{1}+\frac{2.2^2}{2!})\\\\=0.6227

\to x \sim emp(\frac{1}{2.2})\\\\\to f(x)=\frac{1}{2.2} emp1-\frac{x}{2.2}

\to p(x \leq 2)=\int^{2}_{0} \frac{1}{2.2} emp1(-\frac{x}{2.2}\ dx

                  =1-emp1-2|2.2\\\\=0.5971
