Ansible: run multiple action

I am running ansible to copy and execute the script on remote side if script not found. but I am getting this error.

ERROR! conflicting action statements: copy, command

How can i use multiple action in single task.

- name: Check if the bb.sh exists
  stat:
    path: /tmp/bb.sh
  register: stat_result

- name: Copy and execute script
  copy: src=sync/bb.sh dest=/tmp/sync/ mode=0755
  command: sh -c "/bin/sh /tmp/bb.sh"
  when: stat_result.stat.exists == False
