I have this table:
x | 0 1 2 3 4 5 ------------------------------------------ f(x) | .7 .2 .05 .03 .01 .01 F(x) | .7 .9 .95 .98 .99 1
Where f(x) is the density function for x and F(x) is the cumulative distribution function for x.
And I am being asked to use F to verify that P[X=3]=0.03
My guess is that I should start with P[X=3]=F(2) ... something ... something, since F(x)=P(X<=x) but I am not sure.
Any suggestions?
