there are 12 students working in a library if three Fourth of them are girls how many girls are working in the piano

1 answer:

3 0

I don’t really get your question, because you said that ¾ of them are girls, Then how many girls are working in the piano? You did not stated the question well. However, I will try to answer this base on my understanding. There are a total of 12 students that works in the library. IF ¾ of them are girls: => 12 / 4 = 3 *3 = 9 => 9 of them are girls and 3 of them are boys. Thus, how many girls are working in the piano. The probability is 9, there might be 9 girls working in the piano, or less than 9. Since you did not mention how many girls worked in different part of the library.

Orange box:

The incorrect statement is B. The theoretical probability is the probability of an event occurring that is expected. In this case, the theoretical probability of selecting a dime is 4/25.

Purple box:

The incorrect statement is C. The difference between the theoretical and experimental probability is not 1/10. The difference between the experimental and theoretical probability is 0.015 or 3/200.

6/25 = 0.24

9/40 = 0.225

0.24 - 0.225 = 0.015

Hope this helps!! :)
