westside highs 2015 senior - class science enrollment is summarized by the venn diagram. chemistry, biology, and physics class enrollments are denoted by the sets c, b, and p, respectively. how many students are in the 2015 senior class? how many students are taking chemistry and biology, but not physics? how many students are not taking science?
Answer
Explanation:
Step1: Calculate total students in science - related classes
Add up all the numbers within the circles representing Chemistry (C), Biology (B), and Physics (P). $9 + 5+11 + 3+6 + 4+7=45$
Step2: Find total number of students in the senior - class
The number of students in the senior - class is the sum of students in science - related classes and those not taking any of the three sciences. $45+18 = 63$
Step3: Determine students taking Chemistry and Biology but not Physics
Look at the intersection of C and B that is not part of P. The number is 5.
Step4: Identify students not taking science
The number outside all the science - related circles is 18.
Answer:
How many students are in the 2015 senior class? 63 How many students are taking chemistry and biology, but not physics? 5 How many students are not taking science? 18
