Answer:

  • 3/68

Step-by-step explanation:

Given

  • Total 17 marbles
  • 4 - blue marbles
  • 6 - green marbles
  • 2 - red marbles
  • The rest - yellow marbles

Probability of drawing red first:

  • P(red) = number of red / total number = 2/17

Probability of drawing green second, without replacement:

  • P(green) = number of green / number left in the bag = 6/16 = 3/8

Probability of red and green in order:

  • P = P(red)*P(green) = 2/17*3/8 = 3/68
