It is not 50/50, despite popular belief. Research by Stanford University students have found that the actual odds are more 51/49, depending on:
There are 4 possible outcomes, HH, HT, TH, TT. If we assume the odds of tossing heads or tails on any toss is 1/2 (50:50) the odds of tossing heads twice in a row is 1/4 (or 25%).
the only combination which does not produce heads at least once it tails twice. the odds of getting tails twice is 0.5*0.5=0.25 so the odds for getting heads at least once is 1-0.25=0.75 or 75% or 3/4.
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
24 or 16
If this was true, you could simply toss the coin at least 40 times to know whether the statement is (or isn't) valid.
The odds of each coin toss are 50-50. The coin has no memory; there is no record of what the last four tosses are. EVERY toss is at 50-50 odds.
The probability of heads is 1/2.

The odds of getting 3 heads in a toss of 3 coins is 1 in 8, or 0.125. Each coin is probabalistically unrelated to each other, so you simply multiply the odds for each coin. 1 in 2 times 1 in 2 times 1 in 2 is 1 in 8.
The odds are 50/50. A tossed coin does not have a memory.
You are not allowed to cheat in a coin toss. NEVER!

The odds that a tossed coin will land tails side down remain one in two no matter how many times the coin has previously been tossed.
