Oklahoma State's women went 0-for-18 on three-point attempts last night against Texas Tech. That wasn't quite as bad as the Dayton men's 0-for-24 night behind the arc earlier this season, but was still pretty weak.

The Cowgirls entered the game hitting only .321 on trey attempts, which converts to a .679 rate of missing. We then raise .679 to the 18th power (representing the 18 misses), yielding .0009. Rounding up to .001, Oklahoma State's futility behind the arc would have had a prior probability of 1-in-1,000.

This calculation assumes independence of observations, that the outcome of one shot has no bearing on the next, like coin-flipping. A great deal of past research suggests that an independence model generally fits athletic performances well.
