Explanation

HTTP uses port 80 and HTTPS uses port 443. These are the two standard ports for web browsing traffic. Allowing only these two ports restricts the public wireless network to web browsing only, blocking other protocols. Port 20 is FTP data, port 143 is IMAP (email), and port 8080 is an alternate/proxy HTTP port - none of these are the standard HTTP or HTTPS ports required by the question.
