Probability of Drawing Marbles from a Jar

What is the probability of drawing a red marble from a jar that contains 12 red marbles numbered 1 to 12 and 10 blue marbles numbered 1 to 10? The probability of drawing a red marble from the jar can be calculated by dividing the total number of red marbles by the total number of marbles in the jar. In this case, there are 12 red marbles and 10 blue marbles, making a total of 22 marbles.

Calculating Probability of Drawing a Red Marble:

Total number of marbles: 12 red marbles + 10 blue marbles = 22 marbles

Probability of drawing a red marble: 12 red marbles / 22 total marbles = 6/11

Therefore, the probability of drawing a red marble from the jar is 6/11. What is the probability of drawing a blue marble from the same jar? Similar to the calculation for drawing a red marble, the probability of drawing a blue marble can be determined by dividing the total number of blue marbles by the total number of marbles in the jar.

Calculating Probability of Drawing a Blue Marble:

Total number of marbles: 12 red marbles + 10 blue marbles = 22 marbles

Probability of drawing a blue marble: 10 blue marbles / 22 total marbles = 5/11

Thus, the probability of drawing a blue marble from the jar is 5/11.
