ONE COMMON PROPOSAL FOR BEATING THE LOTTERY IS TO NOTE WHICH NUMBERS HAVE COME UP LATELY, ELIMINATE THOSE FROM

CONSIDERATION, AND BET ON NUMBERS THAT HAVE NOT COME UP FOR A LONG TIME.

EXPLAIN WHY THIS IS FAULTY REASONING AND WHAT THIS IS REFERRED TO IN STATISTICS.

Page 8: DAY 2 OF CHAPTER 13 NOW LET’S THINK ABOUT FAMILIES WITH 3 CHILDREN A) CREATE A SAMPLE SPACE OF EQUALLY LIKELY OUTCOMES B) WHAT’S THE PROBABILITY A 3-CHILD.

THE LAW OF AVERAGES IS FALSE.

THE RANDOM METHODS FOR SELECTING LOTTERY NUMBERS HAVE NO MEMORY OF PREVIOUS PICKS,

SO THERE IS NO CHANGE IN THE PROBABILITY THAT A CERTAIN NUMBER WILL COME UP.
