Answer:

P(x>1)=0.9927

Step-by-step explanation:

From the question we are told that:

Mean \=x =7

Generally the Poisson equation for \=x is mathematically given by

P(x>1)=1-P(x \leq 1)

Therefor

P(x>1)=1-(\frac{e^{-7}*7^0}{0!}+{\frac{e^{-7}*7^1}{1!})

P(x>1)=1-(9.1*10^{-4}+6.3*10^{-3})

P(x>1)=1-(7.3*10^{-3}

P(x>1)=0.9927
