Answer:

15/121.

Step-by-step explanation:

Probability of picking a red = number of reds in the bag / total number of marbles in the bag

= 3 / (3 + 3 + 5)

= 3/11.

Probability of picking a blue = 5/11.

These 2 events are independent so we multiply probabilities, therefore the

Probability of (a red then a blue) = 3/11 * 5 /11

= 15/121.
