Answer :

X represents the number of red balls drawn.


X can take values 0,1,2 or 3


there are total 10 balls


n(S) = total possible ways of selecting 2 balls =


P(X = 0) = P(selecting no red balls) =


P(X = 1) = P(selecting 1 red ball and 2 black balls)


=


P(X = 2) = P(selecting 2 red balls and 1 black ball)


=


P(X = 3) = P(selecting 3 red balls and 0 black ball)


=


Now we have pi and xi.


Following table represents the probability distribution of X :
