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.
