laravel public folder is not showing anything in browser when i go to localhost/laravel3/public path

im in real trouble, i use the composser method to setup laravel on my ubuntu system. its install completely. but when i go to localhost/laravel3/public path it shows nothing, i thing there are some permission to folder problems. i also run following commands to change permissions of laravel3 directory.

 chmod -R 777 /var/www/html/laravel3
sudo chown ateeq:ateeq /var/www/html/laravel3/

when i run ls -l command on terminal it shows folliwng results on terminal for laravel3 directory.

drwxrwsr-x 12 ateeq ateeq        4096 اگست  30 19:02 laravel3

and it shows following results when i run ls -l command from laravel3 directory or inside of this project folder.
