Inside a box are a R10 note, a R20 note, a R50 note and a R100 note. Consider the experiment in which two notes are drawn from the box without replacement. Let π be the random variable that gives the value of the smaller (Rands) note. Construct the probability mass function for π
The total outcomes of drawing two notes from the box =6
They are -{R10,R20},{R10,R50},{R10,R100},{R20,R50},{R20,R100},{R50,R100}
When outcomes are -{R10,R20},{R10,R50},{R10,R100}
When outcomes are -{R20,R50},{R20,R100}
When outcome is {R50,R100}
Therefore the probability mass function for X is as follows:
