dezmondo Posted September 27, 2014 Share Posted September 27, 2014 Can anyone help with this probability question. A friend is looking for the answer. I could maybe have solved this many moons ago.....not now lol. Maths/probability help! Think lottery (1-49) and the fact that you have 1 in 57 (1 in 56.66) chance of matching 3 numbers of 6 being chosen and 6 drawn. NOW?! HERE is the question... What are the odds of STILL matching 3 when 10 are chosen (on paper) BUT still 6 are drawn?? Quote Link to comment Share on other sites More sharing options...

Jonny Posted September 27, 2014 Share Posted September 27, 2014 Are you choosing your 3 before or after the six are drawn? Quote Link to comment Share on other sites More sharing options...
littleboyblue Posted September 27, 2014 Share Posted September 27, 2014 (edited) You mean where the entire set of numbers is 1 to 10 or are you still talking about the lottery i.e. 1 to 49? Edited September 27, 2014 by littleboyblue Quote Link to comment Share on other sites More sharing options...

Scotty CTA Posted September 27, 2014 Share Posted September 27, 2014 What are the odds of STILL matching 3 when 10 are chosen (on paper) BUT still 6 are drawn?? Off the top of my head… the odds should be 3.33333333 times better, so approx. 17-1? Quote Link to comment Share on other sites More sharing options...
dandydunn Posted September 27, 2014 Share Posted September 27, 2014 50% chance Quote Link to comment Share on other sites More sharing options...
littleboyblue Posted September 27, 2014 Share Posted September 27, 2014 Ah, mis-read it earlier. Chance should be six times better than with six selections since there are 20 trebles in six selections but 120 trebles in 10 selections. So, about 9.45/1 ?
