Now 2nd girl come nd she choose wrong dress so probability of that girl to choose wrong dress out of   2 is 1/2.   Now for 3rd girl probability is 1 to choose wrong dress.   So probability tht all the 3 wil not choose der own dress is = 2/3 * 1/2 * 1 = 1/3.   Hence (A) is the correct answer.   1/3nswer : 1/3
