3, 3, 4, 5, 5, 8 & 9

``````                         1st digit , 2nd digit
8 ,                            ==== 6! / ( 2! * 2!) ===180
9,                             ==== 6! / ( 2! * 2!)===180
5 ,         8                ===== 5!/2!===60
5 ,         9                ===== 5!/2!===60

total favourable number of events ===480

total sample space === 7! / ( 2! * 2!) ==== 1260
``````

required probability ==== 480 / 1260 === .38

Upon searching, he comes across a bow and 3 arrows. He can hear the villain speak, and thus tries to take a shot at him. He launches the first arrow, it misses the villain. He then launches the second arrow and it misses by a greater margin.
