Answer:
Red is 3/10
yellow is 1/3
Step-by-step explanation:
since there is 10 marbles all together it will be out of 10
and since there is 3 red marbles the probability is 3/10
but when you take out one of the marbles the total amount of marbles in the bag is 9. since there is 3 yellow marbles in the bag it would be 3/9 which can be simplified to 1/3
