texas Holdem winning hands %

recently we have had quite a few poker nights for corporate entertainment in London,  Leeds, York, and Sheffield. One question I keep getting asked is about the chances of any single hand winning in a pre flop situation.

In Texas Holdem, what are the win % of starting hands?

below is a table – e.g. AA has an 85% chance of winning against 1 player pre flop
