(21 POINTS) (SHOW WORK) You randomly draw a marble from a bag of marbles that contains 88 blue marbles, 55 green marbles, and 88 red marbles. What is the probability you draw a blue or red marble?

The probability is 76.19%.

Step-by-step explanation:

To find the probability of an event happening out of multiple events, add the individual events' probabilities and divide by the single event:

There are 3 events here: drawing a blue marble, a red marble, or a green marble.

Adding up the marbles in the bag, there are a total of 231 to choose from. Divide the sum of the blue marbles and the red marbles by the total number of marbles in the bag to receive the probability of drawing a blue or red marble:

There is a 76.19% chance that you will draw a red or blue marble (and not a green marble).
