MHB Question regarding a probability mass function of a random variable

Click For Summary
To understand the probability mass function of a random variable, it's essential to start with the definitions of mean and variance. Calculating the probabilities for specific outcomes, such as p(0) and p(1), is also crucial. These foundational concepts will guide the analysis of the random variable. A clear grasp of these elements will facilitate further exploration of the probability mass function. Engaging with these basics is the first step in tackling the problem effectively.

You should begin with the definition of mean and variance, and also with finding $p(0)$ and $p(1)$.
