Where is a Nevada Concealed Firearm Permit holder not allowed to carry a concealed weapon?

A Nevada Concealed Firearm Permit holder is not allowed to carry a concealed weapon in a public library, at a public school, or in a casino. While it may be tempting to choose one of these options as the correct answer, it is important to note that the question specifically asks for a location where a permit holder is NOT allowed to carry a concealed weapon. Therefore, the correct answer is all of the above, as permit holders are not allowed to carry concealed weapons in any of these places. Choosing one of the individual options would be incorrect.
