If it's a fair coin, the probability is 0.5 * 0.5 * 0.5 = 12.5%.

Two coins are going to be tossed 780 times Predict the number of times 2 heads will be tossed?
Half the time they will be the same, half the time they will be different. Half of the time that they're the same they will be heads, half the time they are the same they will be tails. It's your homework, YOU figure it out. The way I figure it. There are four options: 1) heads / heads 2) heads / tails 3) tails / heads 4) tails / tails By process of chance, one out of four times both coins will be heads/heads. Therefore 780/4 = 195 times.
What is the probability of a coin landing on heads this is the results hthhhthtthhthtt thhthtthhhhthtt?
Every time you flip a coin it has a 50% probability that it will land on either heads or tails. You would expect to get heads about half the time and tails about half the time. What actually happens could be different from what is expected. You could get heads every time, or tails every time. Or you could get tails 75% of the time and heads 25% of the time. however, your results appear to be what you would expect, approximately 50% heads and 50% tails. You got 16 heads and 14 tails. Your percentage of heads is 16/30 x 100= 53.33... %. Your percentage of tails is 14/30 x 100 = 46.66... %.
What is theromental?
suppose you flipped a coin 100 times you might have flipped heads 50 time and tails 50 times
What is mutually exclusive in probability theory?
two events are mutually exclusive if they cannot occur at the same time. The classic example is a coin toss where you have either heads or tails, but there is NO WAY to have heads and tails at the same time. Heads and tails are mutually exclusive.
How many different outcomes if you roll a die and flip a penny?
If you roll a standard die and flip a penny at the same time, there are 12 possible outcomes. You can find this out quickly by multiplying the number of outcomes of the coin (2) by the number of outcomes of the die (6). Here they are: Heads, 1 Heads, 2 Heads, 3 Heads, 4 Heads, 5 Heads, 6 Tails, 1 Tails, 2 Tails, 3 Tails, 4 Tails, 5 Tails, 6
You toss a coin 5 times and it lands on heads What will it land on the 6th time?
there is a 1/2 chance that it will land on heads and 1/2 chance it will land on tails. it dosent matter what the stats are
What is the outcome if you flip a coin 1 time?
It is either heads or tails.
Is heads good luck on a penny?
No. If you flip a penny (or any other standard coin) a lot of times, on average you'll get heads half the time and tails half the time so neither side is luckier than the other.
If you flip a penny 10000 times will it land half the time on tails and half the time on heads?
Assuming the penny is unflawed, yes it should. The more times you flip it, the closer the split should be to 50/50.
A coin is tossed 4 times. What is the probability of getting tails 4 times in a row?
The probability to get tails once is 1/2 (for a fair coin) The probability to get tails twice = the probability to get it once x the probability to get it a second time The probability to get tails 4 times in a row is (1/2)4=1/16 The probability to get tails n times in a row is (1/2)n=1/2n The same thing is also true for heads (same probability: 1/2 each time)
What is the probability that a coin will land on tails 75 percent of the time if flip four times?
For 4 coin tosses, there are 16 possible outcomes. Tails on 75% of 4 tosses is 3 times tails, and 1 time heads. This occurs in 4 of those 16 possibilities, so the probability is 4/16 = 1/4 (or 25%). But if the question is 'what is the probability that it's tails at least 75% of the time, then you have to add in the 1 where all 4 are tails, then you have 5/16 (or 31.25%).
When a coin is flipped what is the probability that it will come up tails?
The side heads is slightly heavier giving it a greater likely hood of landing on tails.
