			The point at the 50% chance would actually give you the ''median'', rather than the mean.
			I just worked out the correct mean to be about 5.2334. The way to calculate it is:

			(chance of success at 0)(1+(chance of success at 1)(1+(chance of success at 2)*(...)))

			or

			(chance of success all the way to 1)+(chance of success all the way to 2)+(chance of success all the way to 3)+...

			I have put it in. [[Special:Contributions/220.255.2.119\|220.255.2.119]] 16:15, 20 May 2012 (UTC)

			''<font face="serif">"And thus the expected average, per wand, is 4.62 charges before the wand explodes."</font>''

			This was a somewhat tentative estimate; while the other was [[wikipedia:Binomial_probability\|fairly easy]] to calculate (just the odds of it never exploding), this one was driving me nuts because of NetHack clipping it. Pretty sure the overall odds would be whatever averages to 50%<sup>*</sup>. It's just basic algebra to reduce this:

			<math>0.5 = \frac{x^3}{343}</math>

			<math>0.5 \times 343 = x^3</math>

			<math>171.5 = x^3</math>
