PMF is a function which gives you the probability that the random variable takes a particular value. Here, X is your random variable. so what is the probability that X= 1 ?? means what is the probability that a fair coin toss shows HEAD? similarly, what is the probability that X= 0 ?? means what is the probability that a fair coin toss shows TAILS? what is the probability that X takes any other value?? Based on your answers of the above questions, we can make PMF.
