you must know When two or more balls are drawn from a bag containing several balls, there are two ways in which these balls can be drawn.

(i) Without replacement : The ball first drawn is not put back in the bag, when the second ball is drawn. The third ball is also drawn without putting back the balls drawn earlier and so on. Obviously, the case of drawing the balls without replacement is the same as drawing them together.

(ii) With replacement : In this case, the ball drawn is put back in the bag before drawing the next ball. Here the number of balls in the bag remains the same, every time a ball is drawn.

Given question and solution are correct.
