Answer:


P(x>1)=0.9927

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-((e^(-7)*7^0)/(0!)+{(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
