#3Assuming that p(heads) = p(tails) = 0.5, probability of not getting 3 heads and 3 tails is given by 1 - probability(3 heads in 6 tosses).
1 - p(3 Heads) = 1 - (6 choose 3)*p(heads)^3*p(tails)^3 = 1 - (6 choose 3)*(.5)^3*(.5)^3 = 11/16 = 68.75%Comment -

#4I did a 'study' i guess you could say on this because i was building a chase system based on a 50% chance. The thing is you have a 50% chance every flip. It doesn't change with past flips because sample sizes are to small.
Great example.
Many people on this forum if they were to flip a coin the rest of their lives would have a streak of 20 heads or 20 tails in a row. Same goes with gambling. It's unpredictable and gambling has no memory. You have about a 50% give or take chance EVERY GAME. It is pretty common to flip a coin heads 6 times in a row believe it or not. I'm pretty sure it will happen within 200 bets.Comment -

#6Believe it or not i must have read your post wrong....i'm sorry. I for some reason thought it was for 6 of the same in a row. shit i have no idea.
I built a 'simulator' in excel and recorder the results of about 500,000 flips at 50% each. The results were crazy. Basically any combination at any time over that many flips. I can't answer your question though, don't have time to think about it i have a test at 8am. Sorry bro!Last edited by tool21; 04-01-08, 12:05 AM.Comment -
