A bag with 12 marbles has 3 red marbles and 5 yellow marbles. A marble is chosen from the bag at random. What is the probability that it is red?

Respuesta :

Answer:

3/12 = 1/4

Step-by-step explanation:

There are 12 marbles in the bag.  If the marble drawn at random is red, it is one of the 3 red marbles.

The probability is "3 out of 12" = 3/12 which simplifies to 1/4.

The probability that it is red would be 1/4
