3. Each member will be responsible for their own transportation.
Sorry, the sentence contains an error. The answer is NO.
"Each member" is singular. "Their" is plural. The sentence should read: "Members will be responsible for their own transportation" or "Each member will be responsible for his or her own transportation."
If you have a choice, the former is better as it avoids the awkward "his or her" construction.
