always because the opposite of a positive is a negative, and the opposite of a positive is a negative. But zero is neither positive or negative, therefore is has no real opposite and is zero.

Answer: 0.0516
Step-by-step explanation:
Given : The number of defective components produced by a certain process in one day has a Poisson distribution with a mean of
.
The probability mass function for Poisson distribution:-![P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%5Cdfrac%7Be%5E%7B-%5Clambda%7D%5Clambda%5Ex%7D%7Bx%21%7D)
For x= 15 and
, we have
![P(X=x)=\dfrac{e^{-20}(20)^{15}}{15!}=0.0516488535318\approx0.0516](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%5Cdfrac%7Be%5E%7B-20%7D%2820%29%5E%7B15%7D%7D%7B15%21%7D%3D0.0516488535318%5Capprox0.0516)
Hence, the probability that exactly 15 defective components are produced in a particular day = 0.0516
