Question

John has a bag of different colored marbles. He has 6 red marbles, 3 blue marblos, 7 yellow marbles, and 5 green marbles. If John reaches into the bag and randomly pulls out a marble, what is the

probability that the marble will be blue? (If necessary, round to the nearest tenth )

Answer 1

The probability of John pulling a blue marble from the bag is 3 out of 21, which is approximately 0.1 or 10% when rounded to the nearest tenth.

Step-by-step explanation:

The student has asked about the probability that John will pull a blue marble from a bag containing a total of 21 marbles of various colors. To find the probability of John pulling out a blue marble, we calculate the ratio of the number of blue marbles to the total number of marbles.

John has 3 blue marbles out of a total of 21 marbles (6 red + 3 blue + 7 yellow + 5 green = 21 marbles). To determine the probability, divide the number of blue marbles by the total number:

Probability = Number of blue marbles / Total number of marbles

Probability = 3/21

To express this probability as a decimal, divide 3 by 21, which gives us 0.142857. If rounding to the nearest tenth is necessary, the result is approximately 0.1 or 10%.

Therefore, the probability that the marble John pulls out will be blue is 0.1 or 10% when rounded to the nearest tenth.

Answer 2

3/21, 14.29%, or 14.29

Step-by-step explanation:

John has 21 total marbles, which includes 3 blue ones.

(That's 3 over 21)

Hope this helps!
