In cases like this, i.e. when you could pick every marble with the same probability, you compute the probability of picking a specific marble colour by dividing the number of favourable outcomes by the total number of outcomes.
The number of favourable outcomes is 3, because there are 3 blue marbles.
The total number of outcomes is 12, because there are 12 marbles in total.
The answer to your question is true
