Container B has a greater probability of picking a yellow marble.
Step-by-step explanation:
You may think that the answer is container A, but it's not. Container A has 15 total marbles. Container B has 10 marbles, and 70% of those 10 marbles, are yellow.
Step-by-step explanation: you have 7 yellow marbles and then to get your denominator you have to add up all the marbles from container a and container b and you will get 25.
