Box 23 - DEAL

Contents - DOUBLE

Lisa's winnings go up to £10,000

Excellent answer for box 23

Interesting decision making at 3 box and with Box 23. If you're prepared to take a risk, here's your options:

73% chance of £10,000 (factoring in Box 23 if you fail)
27% chance of next to nothing
EV = £7,300

20% chance of £15,000
20% chance of £10,000
20%is a chance of £5,000
20% chance of £2,500
20% chance of NOTHING
EV = £6,500

The question is are you willing to sacrifice a 33% chance of winning more to possibly triple your winnings and reduce your chances of crashing by 7%? The more I look at it the more favorable it looks to play the board one more box. I definitely understand Lisa viewing the latter as more desirable; however, and I'm glad she called it right in the end.

Fair result from reasonable decisions.
