A box contains 3 red, 4 blue, and 5 green marbles. What is the probability of drawing a blue marble at random?
a.1/3
b.3/12
c.5/12
d.4/12
Explicación
Probability equals favorable outcomes over total outcomes: 4 blue out of 12 total, or 4/12. This reduces to 1/3, but 4/12 correctly names the direct count. Probability ranges from 0 to 1.
