Answer:
First bag: 1/4. Second bag 1/4
Step-by-step explanation:
Bag one have one red marble and 3 blues, which represent a quarter of the total amount, so if the blue marbles are three quarters, the possibility of picking a red one is of one quarter.
The same applies to the second bag, you have a total of 8 marbles and 2 of them are red, that represents a total of one quarter.
The possibilities of picking a red marble in bag A and B are the same: 1/4 one quarter
