Answer:
The probabilty of selecting a red or yellow marble is 7/12
Step-by-step explanation:
To know the probability we have to divide the number of favorable events by the number of possible events
F = Favorable events: red or yellow marble
P = Possible events: red, yellow or blue
F = 4 + 3
F = 7
P = 5 + 4 +3
P = 12
7/12
The probabilty of selecting a red or yellow marble is 7/12
