Step-by-step explanation:
6)The experimental probability is 39%.(39/100(100)).
7) The theoretical probability is theoretical. This is when something should happen without taking external forces into account. Experimental probability is taking the external forces into account which is why the probability is not as clean cut.
The theoretical probability should be 33%.
The experimental probability is actually 39%.
Answer:
Carlos has practiced piano for 
hours.
Carlos needs to practice 
hours.
Step-by-step explanation:
We have been given that Carlos wants to practice piano 2 hours each day. He practices piano for 3/4 hour before school and 7/10 hour when he gets home.
First of all, we will find piano practiced before school and after school by adding both amounts as:
Make a common denominator:
Add numerators:
Therefore, Carlos has practiced piano for hours.
Now, we will subtract from 2 find number of hours Carlos needs to practice to reach his goal.
Therefore, Carlos needs to practice hours before going to bed in order to meet his goal.
