Final answer:
To find the percentage of CCSF students taking both Biology and English, we use a Venn Diagram calculation, which indicates 20% of students take both subjects. However, this result does not match any of the given options, which suggests there might be an error in the question or the options provided.
Step-by-step explanation:
To determine the percentage of CCSF students that take both Biology and English, we need to analyse the given information using a Venn Diagram. Here's how it's done:
- Total percentage of students taking at least one course: 100% - 17% (percentage taking neither) = 83%.
- Percentage taking Biology: 28%.
- Percentage taking English: 75%.
Now, add the individual percentages of Biology and English and subtract the total percentage taking at least one course:
(Percentage taking Biology) + (Percentage taking English) - (Total taking at least one course) = (28% + 75%) - 83% = 103% - 83% = 20%.
This 20% represents the percentage of students that are double-counted, those that take both Biology and English. Thus, according to the choices given:
The nearest value to 20% which is a possible answer is 20% itself, but as per the given options, we need to select the closest correct option. Since none of the options is close to 20% and it seems there's a typo or mistake in the provided options, we need to clarify this discrepancy before providing a final answer.
