a bag holds 6 green 4 red 5 yellow and 3 purple marbles what is the probability of choosing a purple marble

3/18 = 1/6

To find the probability of choosing a purple marble from the bag, we need to know the total number of marbles in the bag.

The total number of marbles in the bag is given by the sum of the number of green, red, yellow, and purple marbles:

Total number of marbles = 6 (green) + 4 (red) + 5 (yellow) + 3 (purple) = 18 marbles

Since we want to find the probability of choosing a purple marble, we need to determine the number of purple marbles in the bag, which is given as 3.

Now, we can calculate the probability:

Probability of choosing a purple marble = Number of purple marbles / Total number of marbles = 3 / 18 = 1/6

Therefore, the probability of choosing a purple marble from the bag is 1/6 or approximately 0.1667.
