.
answer?
The experimental probability that the next marble will be red is 3/20 or 0.15 or 15%.
whats the answer to You randomly draw a marble from a bag, record its color, and then replace it. You draw a red marble 17 out of 20 times. What is the experimental probability that the next marble will be red? Write your answer as a fraction, decimal, or percent.
The experimental probability that the next marble will be red is
The experimental probability that the next marble will be red is also 17/20 or 0.85 or 85%.
whats the answer too There are 3 red marbles and 10 silver marbles in a bag. You randomly choose one of the marbles. What is the probability of choosing a red marble? Write your answer as a fraction in simplest form.
The probability of choosing a red marble is
The probability of choosing a red marble is 3/13 (three red marbles out of 13 total marbles in the bag).
what is the answer too There are 4 yellow marbles and 9 blue marbles in a bag. You randomly choose one of the marbles. What is the probability of choosing a yellow marble? Write your answer as a fraction in simplest form.
The probability of choosing a yellow marble is
The probability of choosing a yellow marble is 4/13 (four yellow marbles out of 13 total marbles in the bag).
To calculate the experimental probability that the next marble will be red, we need to use the information given: out of 20 times of drawing, the red marble was drawn 3 times.
The experimental probability is calculated by dividing the number of times a specific outcome occurred by the total number of trials. In this case, the outcome is drawing a red marble, which occurred 3 times out of 20 trials.
So, the experimental probability of drawing a red marble is 3/20.
Expressing this as a decimal, we divide 3 by 20:
3 ÷ 20 = 0.15
Lastly, to express it as a percentage, we multiply the decimal by 100:
0.15 × 100 = 15%
Therefore, the experimental probability that the next marble will be red is 3/20, 0.15, or 15%.
