The probability of the coin landing "head" side up is 50/50, meaning it could land "head" side up or "tail" side up. The odds of any single coin flip are always the same, no matter what happened on the previous tosses -- provided the coin is not a "double-head" (or "double-tail") "trick" coin

Tossing a coin 9 times and getting tails what is the probability of getting tails on the next toss?
Since each event is independent, the probability remains at 0.5.
You count 58 heads when you toss a coin 10 times. If you don't know whether the coin is fair what is the probability that the next toss will be heads?
If you toss a coin 10 times and count 58 heads, you know the coin is NOT fair.
What is the probability that I'll get heads on the next toss if I tossed a coin fifteen times and got heads twelve?
The odds are 50/50. A tossed coin does not have a memory.
Is flipping a quarter and a penny a dependent event?
No. Each flip of each coin is an independent event. The flip of the quarter has no effect on the flip of the penny and vice versa. Also, the previous flip of either coin has no effect on the next flip.
If 1 percent of the bolts made by an automotive factory are defective what is the probability that in a shipment of 175 bolts there are 6 defective bolts?
If 1% of the bolts are defective, then the probability is that close to 2 bolts will be defective if there are 175 bolts. The actual probability is that 1.75 bolts will be defective, but you can not have 3/4 of a bolt. However you know there are going to be runs when you have no errors and runs when you have several error. You would need to make 300 bolts in order to have a run of 125 with no errors to have 3 defective bolts in a run of 1.75 bolts. Likewise, you would need to make a minimum of 600 bolts to have six defective bolts in 1.75 bolts. Then you would have 425 good bolts. However, you are dealing with probabilities, not with getting the machinery started the first thing in the morning. Since there is a 1% error rate, you must assume this is a random rate. It occurs like dice or a coin flip. With the last coin tossed, you have no idea what the next coin flip will be. It is not like the next coin flip will be the opposite. Using the Monte Carlo method, I got .29%. Good luck
What is the probability that the next coin flip will come up heads?
If it is a fair coin then the probability is 0.5
You toss a fair coin 5 times and get 5 consecutive heads. What is the probability of tossing a head on the next toss?
If it is a fair coin, the probability is exactly 50%. The coin has no memory of what it did in the last flip. ■
If you flip a coin and get 9 heads in a row what is the probability of getting heads on the next flip?
50%.
Karina tossed a coin 10 times and got heads every time what is the probability she will get heads on the next toss?
Coin tosses are independent events. The probability of a head remains 1/2

Since each event is independent, the probability remains at 0.5.

If you toss a coin 10 times and count 58 heads, you know the coin is NOT fair.
What is the probability that I'll get heads on the next toss if I tossed a coin fifteen times and got heads twelve?
The odds are 50/50. A tossed coin does not have a memory.
What is the probability of getting tails twice in a row?
The probability of tossing a coin twice and getting tails both times is 1 in 4, or 25%. If you have already tossed a coin and had it land on tails, the probability that it will land on tails again the next time you toss it is 50%.
Can someone give me one interesting fact about probability?
If you have tossed a fair, balanced coin 100 times and it has landed on HEADS 100 consecutive times, the probability of tossing HEADS on the next toss is 50%.
Is flipping a quarter and a penny a dependent event?
No. Each flip of each coin is an independent event. The flip of the quarter has no effect on the flip of the penny and vice versa. Also, the previous flip of either coin has no effect on the next flip.
During an experiment a person tosses a fair coin ten times and got six heads What is the probability the coin will land showing heads on the next toss?
It is 1/2.
What is the probabilty that a coin will land on heads if flipped 8 times?
This is a probability question. Probabilities are calculated with this simple equation: Chances of Success / [Chances of Success + Chances of Failure (or Total Chances)] If I flip a coin, there is one chance that it will land on heads and one chance it will land on tails. If success = landing on heads, then: Chances of Success = 1 Chances of Failure = 1 Total Chances = 2 Thus the probability that a coin will land on heads on one flip is 1/2 = .5 = 50 percent. (Note that probability can never be higher than 100 percent. If you get greater than 100 you did the problem incorrectly) Your question is unclear whether you mean the probability that a coin will land on head on any of 8 flips or all of 8 flips. To calculate either you could write out all the possible outcomes of the flips (for example: heads-heads-tails-tails-heads-tails-heads-heads) but that would take forvever. Luckily, because the outcome of one coin flip does not affect the next flip you can calculate the total probability my multiplying the probabilities of each individual outcome. For example: Probability That All 8 Flips Are Heads = Prob. Flip 1 is Heads * Prob. Flip 2 is Heads * Prob. Flip 3 is Heads...and so on Since we know that the probability of getting heads on any one flips is .5: Probability That All 8 Flips Are Heads = .5 * .5 * .5 * .5 * .5 * .5 * .5 * .5 (or .58) Probability That All 8 Flips Are Heads = .00391 or .391 percent. The probability that you will flip a heads on any of flips is similar, but instead of thinking about what is the possiblity of success, it is easier to approach it in another way. The is only one case where you will not a heads on any coin toss. That is if every outcome was tails. The probability of that occurring is the same as the probability of getting a heads on every toss because the probability of getting a heads or tails on any one toss is 50 percent. (If this does not make sense redo the problem above with tails instead of heads and see if your answer changes.) However this is the probability of FAILURE not success. This is where another probability formula comes into play: Probability of Success + Probability of Failure = 1 We know the probability of failure in this case is .00391 so: Probability of Success + .00391 = 1 Probability of Success = .9961 or 99.61 percent. Therefore, the probability of flipping a heads at least once during 8 coin flips is 99.61 percent. The probability of flipping a heads every time during 8 coin flips is .391 percent.
