Understanding the Probability Behind the Marble Draw
To calculate the probability that both drawn marbles are green, begin with the total number of marbles in the bag: 4 red + 5 blue + 6 green = 15 marbles total. Drawing two marbles at random means considering combinations—how many unique pairs can be formed. The total number of ways to choose 2 marbles from 15 is given by the combination formula C(15, 2), which equals 105 distinct pairs. Only the combinations where both marbles are green contribute to the desired outcome. With 6 green marbles, the number of ways to pick 2 green marbles is C(6, 2) = 15. This gives a basic probability of 15/105, which simplifies to 1/7—about 14.3%. Understanding this step-by-step breakdown builds clarity and trust, essential for spreading accurate knowledge.
