While watching the fourth season of House of Cards I have been reminded of the 50-50-90 rule: Anytime you have a 50-50 chance of getting something right, there’s a 90% probability you’ll get it wrong. House of Cards is a Netflix series depicting political intrigue and mayhem in Washington, D.C. Season four is set in the 2016 election season, which is a bit tedious, considering all the real political stuff we watch in our home. An amusing (to me) back story this season is that oil prices are through the roof, and we see a replay of the 1970’s gas shortage.
