What is the meaning of the term heads and tails for the example when one tosses a coin to make a choice?
It means just what it seems to -- someone tosses a coin up and you try to guess which side will be facing up when it lands. "Heads" is the side with the person's face on it and "tails" is other side.
A coin is tossed twice if heads comes up either time you get 2 if heads does not come up you lose 4?
This is a good bet to take. Your expected payout is 0.5 each round of the 2 tosses. The possible outcomes from 2 tosses: HT, HH, TT, TH. The probability that heads comes up is 3 in 4 (.75). The probability that heads does not come up is 1 in 4 (.25). Your expected payout is: (2 * .75) + (-4 * .25) = 1.5 - 1 = 0.5
What is the probability that a coin will turn up heads twice in 6 tosses of the coin?
Every time a coin is tossed there is a 50 / 50 chances of it coming up heads. There is no rule that says tossing it 100 or 6 times will change this.
Sarah tosses 25 coins 3 out of every 5 are heads up and the rest are tails upHow many coins are tails up?
10 coins would be tails up.
What is the probability that a coin lands heads up on three consecutive tosses?
For each toss, the probability that it'll land heads up is 1/2 So 1/2 * 1/2 * 1/2 = 1/8, or .125 There is a 12.5% chance that it will land heads-up all 3 times.

When a fair coin is tossed 10 times in a row what is the probability that heads comes up at least once?
Pr(H at least once in 10 tosses) = 1 - pr(No H in 10 tosses) = 1 - Pr(10 T in 10 tosses) = 1 - (1/2)10 = 1 - 1/1024 = 1023/1024
If a coin and a dice is tossed what is the probaility of getting a heads and six?
Heads comes up half the time, sis one time in six tosses so the combined odds of heads and six is 1/2 x 1/6 = 1/12, one time in 12.
In four successive tosses a fair coin lands heads up each time What is likely to happen when the coin is tossed a fifth time?
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.
When a fair coin is tossed 20 times in a row what is the probability that heads comes up 10 times in a row somewhere in the 20 tosses?
The probability of 10 heads in a row is (0.5)10 = 0.000977 = 0.0977% .It makes no difference what has come before or what comes after.
If a coin is tossed 3 times what is the probability of 3 heads?
There are 8 possible outcomes when a coin is tossed 3 times. Here they are:1. Heads, Heads, Tails.2. Heads, Tails, Heads.3. Tails, Heads, Heads.4. Heads, Heads, Heads.5. Tails, Tails, Heads.6. Tails, Heads, Tails.7. Heads, Tails, Tails.8. Tails, Tails, Tails.There is only one outcome that is heads, heads, heads, so the probability of three heads coming up in three coin tosses is 1 in 8 or 0.125 for that probability.
What is the probability that all 3 tosses will result in heads?
The probability that a coin will result in heads in any one toss is 1/2. If you toss the coin three times, the probability that the coin will turn up heads each time is 1/2 x 1/2 x 1/2 or 1/8, which is 12.5%.
