120 = Dealing Probability and Healing Gullibility

🃏 What are the odds of actually winning Morgan’s very specific, very fun card game?

🤯 Are people more gullible now? And what are the best ways to persuade someone they are wrong?

👻 And, appropriate to the season, there will be some Any Other Boooooooooooooosness

If you have some ingenious suggestions of what Matt can do in lunar gravity, head to www.aproblemsquared.com and submit your idea as a ‘Solution’

Head to our socials to see Matt’s graph plot and stats on the odds of winning the card game, as well as Bec’s beautifully laid out existence proof of the 52 Card Game!
