In classic Barker fashion, Bob claims this is the first time this happened -- but it had previously occurred on March 18, 1980 -- AND October 20, 1983!
I think it's a 3/105 probability. The chance of drawing a strike on the first turn is 3/7, on the second 2/6 (or 1/3), and on the third turn 1/5. Multiply them all together and you get 3/105.
@@VectraQS That only with the chance to get strike Another difficult thing is you had to guess the position of that number With 6 numbers, there 720 results(If there no "0") With 4 numbers, there 24 results(If there no "0") With 5 numbers, there 120 results(If there no "0")
