To determine how many white marbles are in the bag, we need to use the information provided in the clues.
Based on the clues given, we know that the bag contains 12 marbles in total. The probability of selecting a white marble is equal to 1/4. This means that 1 out of every 4 marbles in the bag is white.
To find out how many white marbles are in the bag, we can set up a proportion:
x/12 = 1/4
Multiplying both sides by 12, we get:
x = 12/4
x = 3
Therefore, there are 3 white marbles in the bag.
