A bag contains 5 red marbles, 8 blue marbles, and 7 green marbles. If a marble is randomly selected from the bag, what is the probability that it is either red or green?
To solve this, you can use the formula for the probability of an event ( P(E) ):
P(E)=Number of favorable outcomesTotal number of possible outcomesP(E)=Total number of possible outcomes
