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.
