### When a coin is tossed three times what is the probability of getting at most two heads?

The opposite of getting at most two heads is getting three heads. The probability of getting three heads is (1/2)^2, which is 1/8. The probability of getting at most two heads is then 1 - 1/8 which is 7/8.

### What is the probablity that the sequence will be heads-heads-heads if you toss a coin 3 times?

the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.

### A coin is tossed five times find the probability of getting exactly three heads?

Since a coin has two sides and it was tossed 5 times, there are 32 possible combinations of results. The probability of getting heads three times in 5 tries is 10/32. This is 5/16.

### What is the probability of flipping a coin 3 times and getting 3 heads?

The probability of flipping a coin 3 times and getting 3 heads is 1/2

### What is the probability of tossing a coin three times and getting it on heads each time?

Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of:1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5%

### What is the probability of getting all heads or all tails if you flip a coin three times?

The probability of getting all heads if you flip a coin three times is: P(HHH) = 1/2 &#8729; 1/2 &#8729; 1/2 = 1/8. The probability of getting all tails if you flip a coin three times is: P(TTT) = 1/2 &#8729; 1/2 &#8729; 1/2 = 1/8. The probability of getting all heads or all tails if you flip a coin three times is: P(HHH or TTT) = P(HHH) + P(TTT) = 2/8 = 1/4.

### What is the probability that a coin that is tossed 10 times what is the probability of it landing on heads 10 times?

The probability is 0.09766%.Each toss has a &frac12; chance to be heads. To combine probabilities use multiply them. So the probability to get two heads out of two tosses is &frac12; * &frac12;, and three heads out of three tosses is &frac12; * &frac12; * &frac12;. So the exact answer is 0.5^10

### What is the probability is of getting 3 heads in a row if I toss the coin 10 times?

The probability of getting 3 or more heads in a row, one or more times is 520/1024 = 0.508 Of these, the probability of getting exactly 3 heads in a row, exactly once is 244/1024 = 0.238

### What is the probability of flipping a coin 4 times and getting 4 heads?

You still still have a 1:2 chance of getting heads regardless of the times you flip.

### Tiree tossed a coin 100 times and got 70 heads. how does her probability compare to the mathematical probability?

The mathematical probability of getting heads is 0.5. 70 heads out of 100 tosses represents a probability of 0.7 which is 40% larger.

### What is the probability of getting heads three times in a row when tossing a coin?

Ideally, the probability of getting any specific combination of length n is 0.5n = 1/2n. For n = 3, this is 0.125 = 1/8.

### If you toss a coin 3 times what is the probability that it will land on heads 3 times?

The probability of getting heads on three tosses of a coin is 0.125. Each head has a probability of 0.5. Since the events are sequentially unrelated, simply raise 0.5 to the power of the number of tosses (3) and get 0.125, or 1 in 8.

### What is the probability of getting exactly 3 heads if a fair coin is tossed 8 times?

The probability to get heads once is 1/2 as the coin is fair The probability to get heads twice is 1/2x1/2 The probability to get heads three times is 1/2x1/2x1/2 The probability to get tails once is 1/2 The probability to get tails 5 times is (1/2)5 So the probability to get 3 heads when the coin is tossed 8 times is (1/2)3(1/2)5=(1/2)8 = 1/256 If you read carefully you'll understand that 3 heads and 5 tails has the same probability than any other outcome = 1/256 As the coin is fair, each side has the same probability to appear So the probability to get 3 heads and 5 tails is the same as getting for instance 8 heads or 8 tails or 1 tails and 7 heads, and so on

### A fair coin is flipped 4 times what is the probability of getting more than 3 heads?

The probability of flipping a fair coin four times and getting four heads is 1 in 16, or 0.0625. That is simply the probability of one head (0.5) raised to the power of 4.

### The probability of flipping a coin three times and getting two heads is?

There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.

### What is the probability of tossing a fair coin ten times and getting ten heads in a row?

Answer this Question : Probability of getting 10 heads in a row is(1/2)^10 = 1/1024 = 0.000976 or 0.098 %

### If you toss 4 coins what is the probability of getting four heads and zero tails?

The probability of getting a head is 1/2 and if you toss it 4 times, the probability of 4 heads is (1/2)^4=1/16 since the tosses are independent events.

### What is the probability of flipping a coin twice and getting two heads?

The probability is 25%. The probability of flipping a coin once and getting heads is 50%. In your example, you get heads twice -- over the course of 2 flips. So there are two 50% probabilities that you need to combine to get the probability for getting two heads in two flips. So turn 50% into a decimal --&gt; 0.5 Multiply the two 50% probabilities together --&gt; 0.5 x 0.5 = 0.25. Therefore, 0.25 or 25% is the probability of flipping a coin twice and getting heads both times.

### What is the probability of getting three tails if you flip a coin three times?

Since the probability of getting tails is 50% or 0.5, the probability of three tails would be 0.5*0.5*0.5=0.125 or 12.5 %
