What are the odds of getting heads at least once if I toss a coin twice?
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.
What are the odds of getting heads twice in a row with a coin?
"The same as getting heads the first time, a one-in-two chance." No It's Not! "One in two chance" means 50/50 chance. The odds of getting 2 in a row are not 50/50. I don't know what it is because that's how I arrived at this question. But if my friend were to bet me that he could get to heads in a row.... I'd take him up on that bet everytime, saying that he couldn't. He'd win a couple times here and there but in the end would lose money. It's not 50/50.
If you flip a a coin 20 times what is the probability that the coin will land on heads?
There is a fifty percent chance of the coin landing on "heads" each time it is flipped.However, flipping a coin 20 times virtually guarantees that it will land on "heads" at least once in that twenty times. (99.9999046325684 percent chance)You can see this by considering two coin flips. Here are the possibilities:Heads, heads.Heads, tails.Tails, tails.Tails, heads.You will note in the tossing of the coin twice that while each flip is fifty/fifty, that for the two flip series, there are three ways that it has heads come up at least once, and only one way in which heads does not come up.In other words, while it is a fifty percent chance for heads each time, it is a seventy five percent chance of seeing it be heads once if you are flipping twice.If you wish to know the odds of it not being heads in a twenty time flip, you would multiply .5 times .5 times .5...twenty times total. Or .5 to the twentieth power.That works out to a 99.9999046325684 percent chance of it coming up heads at least once in the twenty times of it being flipped.

One in four. 1:4. The probability of getting heads when a fair coin is tossed is: P(H) = 1/2.
