value of t. For example- A fair coin is tossed 3 times Sample Space = {HHH , HHT , HTH , HTT , THH , THT , TTH , TTT} X= Number of heads X ∈ {0,1,2,3} Fₓ(0) = 1/8 Fₓ(1)=3/8 Fₓ(2)=3/8 Fₓ(3)=1/8 This shows the PMFs of various discrete random variables. The main thing to remember about PMF is that sum
