There are 35 marbels in a bag: 9 blue marbels, 8 green marbels, 4 red marbels, 8 white marbels, and 6 yellow marbels. Find P(red). Write the probability as a fraction in simplest form, a decimal, and a percent.
A. 4\31,0.129,12.9%
B. 4\35,0.114,11.4%
C. 1\7,0.143,14.3%
D. 3\32,0.086,8.6%
Is the answer B?
Thank you
P(red)=numberReds/Total=4/35
yes, B
Yes, it's B.
Thank you
To find the probability of an event, you divide the number of favorable outcomes by the total number of possible outcomes. In this case, the favorable outcome is selecting a red marble, and the total number of possible outcomes is the total number of marbles in the bag.
The number of red marbles is given as 4, and the total number of marbles in the bag is given as 35.
To express the probability as a fraction, you write the number of favorable outcomes (4) as the numerator, and the total number of possible outcomes (35) as the denominator. So, the probability as a fraction is 4/35.
To express the probability as a decimal, you divide the number of favorable outcomes (4) by the total number of possible outcomes (35). So, the probability as a decimal is approximately 0.114 (rounded to three decimal places).
To express the probability as a percent, you multiply the decimal probability by 100. So, the probability as a percent is approximately 11.4%.
Comparing the given options:
A. 4/31, 0.129, 12.9%
B. 4/35, 0.114, 11.4%
C. 1/7, 0.143, 14.3%
D. 3/32, 0.086, 8.6%
Based on the calculations, the correct answer is B. The probability of selecting a red marble is 4/35, which is approximately 0.114 or 11.4%.
