A bag contains 8 blue marbles, 6 red marbles, 15 green marbles, and 16 orange marbles. A marble is chosen at random from the bag. What is the probability that the marble is red?
6/(8+6+15+16) = ?
2/15
To find the probability of choosing a red marble, we need to know the total number of marbles in the bag.
The total number of marbles in the bag is the sum of the number of blue, red, green, and orange marbles:
Total number of marbles = 8 (blue) + 6 (red) + 15 (green) + 16 (orange) = 45 marbles
Now, we can calculate the probability of choosing a red marble by dividing the number of red marbles by the total number of marbles:
Probability of choosing a red marble = Number of red marbles / Total number of marbles
Probability of choosing a red marble = 6 / 45 = 2 / 15 ≈ 0.133 or 13.3% (rounded to the nearest tenth of a percent)
Therefore, the probability of choosing a red marble is approximately 0.133 or 13.3%.
To find the probability of selecting a red marble, we need to know the total number of marbles in the bag. In this case, the bag contains 8 blue marbles, 6 red marbles, 15 green marbles, and 16 orange marbles, which adds up to a total of 8 + 6 + 15 + 16 = 45 marbles.
The probability of an event occurring is defined as the number of desired outcomes divided by the number of possible outcomes. In this case, the desired outcome is selecting a red marble, and the possible outcomes are selecting any marble from the bag.
Therefore, the probability of selecting a red marble can be calculated as follows:
Probability of selecting a red marble = Number of red marbles / Total number of marbles
Number of red marbles = 6
Total number of marbles = 45
Probability of selecting a red marble = 6 / 45 = 2 / 15
So, the probability of selecting a red marble from the bag is 2/15.
