It's Only a Flesh Wound

Probability Level 4

King Arthur is in combat with The Black Knight. The Black Knight has four limbs; two arms and two legs. Arthur chooses a limb to strike at randomly and has a 50% chance of cutting the limb off.

The Black Knight will only be stopped when all of his limbs have been removed.

What is Arthur's probability of victory in 10 strikes? (Round your answer to the tenths place.)
