. In a certain school, 30% of the student body is taking a biology class. Of the biology students, 35% have a B in the
class. Of the students taking some other science class, 55% have a B in the class. If a student were selected at
random from the student body of this school, what is the probability that the student is a biology student with a B in
the class?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
