Given, bag contains 3 red and 2 black balls.
Probability of getting red ball=
Probability of getting black ball=
(i) two red balls
P(getting two getting red balls)=P(A)*P(A)
(ii) two black balls
P(getting two black balls)=P(B)*P(B)
(iii) first red and second black ball.
P( getting first red and second black ball)=P(A)*P(B)
