### What is the probability of getting both tails on two tosses of a coin?

The probability of two tails on two tosses of a coin is 0.52, or 0.25.

### If a fair coin is tossed ten times what is the probability of getting five heads?

The probability of getting five heads out of 10 tosses is the same as the probablity of getting five tales out of ten tosses. One. It will happen. When this happens, you will get zero information. In other words, this is the expected result.

### When tossing a fair coin the probability of getting three heads in a row is?

In a large enough number of tosses, it is a certainty (probability = 1). In only the first three tosses, it is (0.5)3 = 0.125

### Find the probability of heads on three consecutive tosses of a coin?

The number of total outcomes on 3 tosses for a coin is 2 3, or 8. Since only 1 outcome is H, H, H, the probability of heads on three consecutive tosses of a coin is 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.

### The experimental probability of a coin landing on heads is 712. if the coin landed on tails 30 timefind the number of tosses?

The experimental probability of a coin landing on heads is 7/ 12. if the coin landed on tails 30 timefind the number of tosses?

### 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 exactly 2 heads in 3 coin tosses?

With 3 coin tosses, the possible outcomes are: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT There are 8 possible outcomes and 3 of them have 2 heads. Thus: probability = 3/8 (= 0.375)

### 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 of getting 3 heads in 10 tosses of a fair coin?

130 instances of 3 heads out of 1024 total possible outcomes=130/1024=0.126953125

### What is the probability of getting heads on all 2 tosses if a fair coin is tossed 5 times?

With 5 coin tosses there are 32 possible outcomes. 10 of these have exactly 2 heads, and 26 of these have 2 or more heads.For exactly two coins are heads: 10/32 = 31.25%For two or more heads: 26/32 = 81.25%

### What is the probability of tossing a coin and getting a head?

The probability of tossing a coin and getting heads is 0.5

### What is the probability of getting two heads in a row followed by three tails in a row?

If you toss a coin often enough, it is a certainty, so that the probability = 1. The probability of that outcome in the first five tosses of a coin is (1/2)5 = 1/32.

### What is the probability of getting heads on the one flip of coin?

There are two sides to the coin, so the probability of getting heads or tails on one flip of the coin is 1/2 or 50%.

Each time you flip a coin, the probability of getting either heads or tails is 50%.

### 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%.

### What is the probability of getting tails if a coin is tossed 4 times?

If you look at the as the probability of getting 1 or more tail in 4 coin tosses, you would then calculate the probability of tossing 4 heads in a row and subracting that from 1. The probability fo tossing 4 heads is 1/2 * 1/2 * 1/2 * 1/2 = 1/16. 1 - 1/16 = 15/16.

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