Answer:
60%
Explanation:
Answer: The answer to your question is 60%
Step-by-step explanation: The total number of marbles in Joseph's bag is:
2 (red) + 4 (green) + 10 (yellow) + 9 (purple) = 25
The probability of choosing one marble that is not yellow can be found by dividing the total number of marbles that are not yellow by the total number of marbles in the bag:
P(not yellow) = (2 red + 4 green + 9 purple) / 25
P(not yellow) = 15/25
P(not yellow) = 3/5
P(not yellow) = 0.6 or 60%
Therefore, the answer is 60%.
