# What is the probability of getting heads when tossing a fair coin?

## What is the probability of getting heads when tossing a fair coin?

50%
For example, the probability of an outcome of heads on the toss of a fair coin is ½ or 0.5. The probability of an event can also be expressed as a percentage (e.g., an outcome of heads on the toss of a fair coin is 50% likely) or as odds (e.g., the odds of heads on the toss of a fair coin is 1:1).

What is the probability of getting four heads when a fair coin is tossed ten times?

The probability is approximately 20.51%.

When tossing 4 coins What is the probability of getting exactly 2 heads?

Thus the probability is: 2/8=0.25 but the correct answer is 0.375.

### What is the probability of getting 4 heads when tossing a coin 8 times?

The 4th head occurs on the 8th toss: There are (73)=35 unique ways this can happen. Each of these unique outcomes has probability 1256, so the probability that the outcome will be in this set is P8=35256.

What is the probability of getting 4 heads in a row?

The probability of getting a heads first is 1/2. The probability of getting 2 heads in a row is 1/2 of that, or 1/4. The probability of getting 3 heads in a row is 1/2 of that, or 1/8. The probability of getting 4 heads in a row is 1/2 of that, or 1/16.

What is the probability of tossing 3 coins?

Solution: When 3 coins are tossed, the possible outcomes are HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. (i) Let E1 denotes the event of getting all tails. Hence the required probability is ⅛.

#### What is the probability of getting exactly 4 heads?

1/16
The probability is therefore 1/16. N=4: There is only one possible outcome that gives 4 heads, namely when each flip results in a head. The probability is therefore 1/16.

What are the chances of getting 4 heads in a row?

The probability of getting 4 heads in a row is 1/2 of that, or 1/16.

What is the probability of getting exactly 3 heads?

Answer: If you flip a coin 3 times the probability of getting 3 heads is 0.125. When you flip a coin 3 times, then all the possibe 8 outcomes are HHH, THH, HTH, HHT, TTH, THT, HTT, TTT.

## How many outcomes are there for tossing 4 coins?

16 possible
Each coin has two possible outcomes – heads or tails. Therefore, the total number of possible outcomes is: 2×2×2×2=16 possible outcomes.

What is the probability of getting at most 4 heads?

The probability of getting 3 heads in a row is 1/2 of that, or 1/8. The probability of getting 4 heads in a row is 1/2 of that, or 1/16.

What is the probability of getting 4 heads when a fair coin is tossed 8?

There are 2^8 (i.e. 256) possible sequences of flips. Since the coin is fair, each of them is equally likely. There are (8 choose 4) sequences where 4 of the flips are heads. Therefore, the likelihood of getting 4 heads is 70/256, or approximately 27%.

### What is the probability of landing 4 heads in 4 tosses?

This means the probability of landing all 4 heads in 4 tosses is 1 out of the 16. So the answer is 1/16. As for the “before flipping a tail”, it doesn’t seem to matter because no matter the outcome there is still only 1 in 16 chances to get 4 heads flipped.

What is the probability of getting 4 heads?

The probability that 4 heads appear doesn’t depend on the order they appear in. For example, getting So we have to take all of those into account. The chances of getting heads each flip is 0.5 (50%), so the chances of getting 4 heads and 4 tails is 0.5^8.

How many times can you flip a coin?

Getting 3 tails is the same as getting 1 head. This is out of 16 total ways to flip a coin 4 times. So the probability is That only happens 2 times. Once in the “3 tails” section which is TTTH and once in the “4 tails” section, which is TTTT.
