Step-by-step explanation:

Given : Total rolls of film in the box = 10

Defective rolls =3

Probability of selecting first defective roll =

Now , total rolls left = 9

Total defective rolls left = 2

Probability of selecting second defective roll =

Now , the probability of selecting a defective roll followed by another defective roll =

Hence, the probability of selecting a defective roll followed by another defective roll is .
