a bag is filled with 4 red marbles, 3 blue marbles,3 yellow marbles, and 2 green marbles. you randomly choose one marble from the bag. (a) find the number of ways the event can occur. (b) find the favorable outcomes of the event

a. 12

b. it depends on the color of the marble.

Step-by-step explanation:

In this case the number of ways would be the number of events, in this case the events would be the total number of marbles since any of them can come out. so:

4 + 3 + 3 + 2 = 12

Therefore, the number of ways the event can occur is 12 ways.

Now, in the favorable outcomes of the event, it would come depending on what color the marble would be, whether it be red, blue, yellow or green.

In each color, the number of the favorable outcomes of the event would be the quantity of each marble, that is, 4 for red, 3 for blue, 3 for yellow and 2 for green.
