Answer:

  • C. 0.08889

Explanation:

Total number of marbles:

  • 5 + 2 + 1 + 2 = 10

There are two possibilities

  • Orange then green or green the orange

The probabilities are:

  • P(o&g) = 2/10*2/9 = 2/45
  • P(g&o) =2/10*2/9 = 2/45

Required probability is:

  • P = 2/45*2 = 4/45 = 0.08889

Correct choice is C
