Answer:
1/8 = .125 = 12.5%
Step-by-step explanation
There is a 1 in 4 chance of picking a red marble out of the first bag, so you have a fraction 1/4. In the second bag, 2 of the 8 total marbles are red, so you have a second fraction, 2/8 or 1/4. In order to find the probability of picking red from both bags, you must multiply the probabilities of picking red from each bag together. 1/4 × 1/4 = 1/8 = 0.125 = 12.5%. Hope this helped :)
