Cruz has collected some marbles. The colors of the marbles are listed below.
• 8 red marbles • 2 blue marbles • 7 yellow marbles • 3 green marbles
Cruz mixes all the marbles in a bag and then turns the bag upside-down so that only one marble falls out at a time. What is the probability that the first marble to fall out will be a blue marble?
What is the probability that the first marble to fall out will be red, yellow, or green?
Okay so your question seperated into 4 question however in all the question you need to add the total sum up. 8+2+7+3=20 Now we can start Blue: There is blue 2 marbles. So your fraction will end up being 2/20 or 1/10 Red: There is 8 red marbles. So your fraction will be 8/20 or 2/5 Yellow: There is 7 yellow marable so your fraction will be 720. Green: 3 green marble so it will be 3/20 ~JZ Hope it helps
