A bag contains 6 red marbles, 2 green, and 4 blue marbles. You randomly pick a marble and then pick a second marble, returning the marbles to. the bag each time. What is the probability of pulling a blue marble first and then a red marble. second?

Probability of pulling a blue marble is 1/3 about 33% chance

Probability of pulling a red marble is 1/2 = 50% chance

Step-by-step explanation:

Total marbles = 6+2+4 = 12

4 of those 12 are blue

4/12=1/3 when reduced

Total marbles are still = 12

6 of the 12 are red

6/12=1/2 when reduced

Hope this helps! :)
