MHB Probability function (p.f) of a random variable

Click For Summary
SUMMARY

The discussion focuses on deriving the probability function (p.f) for a Bernoulli random variable W, which is defined based on a Poisson random variable T with parameter λ. The key relationship established is that P(W=1) equals P(T=0), calculated as P(T=0) = (λ^0 / 0!) * e^(-λ), while P(W=0) is determined as 1 - P(T=0). This establishes a clear method for calculating the probabilities associated with W based on the properties of the Poisson distribution.

If one has a Bernoulli random variable W that is derived from a Variable T (Poisson λ), by the following rules W = (if T=0 then W=1 and if T>0 then W=0), I am having trouble finding the pf for W. Any suggestions about how to proceed forward?

Welcome to the forum.

The distribution for $T$ says that $P(T=0)=\frac{\lambda^0}{0!}e^{-\lambda}$. By assumption $P(W=1)=P(T=0)$ and $P(W=0)=1-P(T=0)$.
 
If there are an infinite number of natural numbers, and an infinite number of fractions in between any two natural numbers, and an infinite number of fractions in between any two of those fractions, and an infinite number of fractions in between any two of those fractions, and an infinite number of fractions in between any two of those fractions, and... then that must mean that there are not only infinite infinities, but an infinite number of those infinities. and an infinite number of those...
