Question

Of the 1055 biologists at a biotechnology company, 267 study insulin production and 62 study biological warfare. If 21 study both insulin production and biological warfare, how many biologists study neither of these subjects?

Answer 1

To find the number of biologists who study neither insulin production nor biological warfare, subtract the number of biologists who study either one of these subjects or both from the total number of biologists.

Step-by-step explanation:

To find the number of biologists who study neither insulin production nor biological warfare, we need to subtract the number of biologists who study either one of these subjects or both from the total number of biologists.

First, we add the number of biologists who study insulin production (267) and the number who study biological warfare (62), which gives us a total of 329.

Next, we subtract the number of biologists who study both insulin production and biological warfare (21). So, 329 - 21 = 308.

Finally, we subtract 308 from the total number of biologists (1055) to find the number of biologists who study neither subject: 1055 - 308 = 747.
