I have 18 blue marbles, 16 green marbles, and 22 red marbles in a bag. What is the chance I will pick a green if I pick a marble at random?
16/(18+16+22) = ?
To find the chance of picking a green marble at random, you need to calculate the probability. The probability is calculated by dividing the number of desired outcomes by the total number of possible outcomes.
In this case, the number of desired outcomes is the number of green marbles, which is 16. The total number of possible outcomes is the sum of all the marbles, which is 18 + 16 + 22 = 56.
Therefore, the probability of picking a green marble at random is:
16 (number of green marbles) / 56 (total number of marbles) = 0.2857 or 28.57% (when rounded to two decimal places).
So, there is approximately a 28.57% chance of picking a green marble if you pick a marble at random.
