Let a random variable   be given by its distribution			
 	X     3       0         1        4
        p    .1      .1        .5       .3
    
    Find the distribution function and draw its graph

random variable X

would that just be the histogram of the freq distribution?

anonymous · Answer

in fact i think the graph is just 4 vertical lines.  the distribution function is 
$$P(X=3)=.1,P(x=0)=.1,P(X=1)=.5,P(X=4)=.3$$

anonymous · Answer

i do not understand the graph as it is written

anonymous · Answer

i think that it is the histogram for the frequency distribution

$$\begin{array}c x\--&-&--&--&--&--&--&-\
.6&|&&&&&&|\
.5&|&&-&&&&|\
.4&|&&-&&&&|\
.3&|&&-&&&-&|\
.2&|&&-&&&-&|\

ok i understand now. I thought that there was a specific equation that had to be written
