Assume that the number of asbestos particles in a squared meter of dust on a surface follows a Poisson
distribution with a mean of 1000. If a squared meter of dust is analyzed, use normal distribution to approximate
the probability that exactly 950 particles are found.
Let P(Z<-1.57)= 0.058; P(Z < -1.60) = 0.055.
