Question

a bag has 6 green, 4 red, 5 yellow and 15 blue marbles what is the possibility that the marble is red or blue

Answer 1

Answer: 19/30 or about 63%

Step-by-step explanation: Add all your marble up so 6+4+5+15 to get the total amount of options or marbles in this case. Now find out how many red and blue marbles you have so 4+15 or 19 now you can divide the red and blue marbles by the total amount of marbles to get your percentage of pulling a red or blue marble from the bag.
