If you want to create a poll on an event that happened in the past, tap the Past tab at the top to view those events.

If prompted, select Post in event to confirm that you want to add the poll to the event, not your news feed. If you don’t see the option to “Say something,” the event host has not permitted you to create posts on the event. This may be because you haven’t yet marked yourself as going to the event. To mark yourself as attending, scroll back up to the top of the event and tap Going.

If you don’t have this option, you may not be using the latest version of the Facebook app. Open the App Store, tap your initials or profile photo at the upper-right corner, and then scroll down to “Facebook. " If you see an Update button, tap it to update Facebook now. This feature may not be available in all regions.

Tap X next to an option if you want to delete it. You can also tap the gear icon to the right of the poll to choose whether members should be allowed to add their own options and/or choose multiple options.

To see who selected a particular answer, tap its number of votes. You can edit the poll answers after posting—just tap the answer and replace it with your desired text. Or, to remove an answer, tap the X to its right.
