What is the probability that at most one tail appears within the three tosses?

There are 8 total possible outcomes for flipping three coins, and 3 of the 8 scenarios have one tail in them (THH, HTH, HHT). The answer is 3/8.

What is the probability of getting at most 1 tail?

Only the middle two possibilities have exactly one tail, so the probability of exactly one tail is 50\%.

What is the probability of getting at most 1 tail if you toss the coin twice?

0.5
As you can see from the picture, the probability of getting one head and one tail on the toss of two coins is 0.5. There are two different ways that this can happen. The first coin can come up heads and the second coin can come up tails, or the first coin can come up tails and the second coin can come up heads.

What is the probability of getting at most 1 head?

Therefore, the probability of getting at most one head = 3/4.

What is the probability of getting at least 1 tail?

As shown above – out of 8 possible combinations all but 1 have at least one tail – making the probability of at least 1 tail to be 7 out of 8, or 87.5 percent. As the toss of each coin is a unique event, then the probability of a tail is 50\% for each and every toss, regardless of the outcomes of the other two coins.

What is the chance of getting at least 1 tail?

Probability of getting at least 1 tail in 3 coin toss is 1−18=78 .

What is the probability of getting a tail?

When we flip a coin there is always a probability to get a head or a tail is 50 percent. Suppose a coin tossed then we get two possible outcomes either a ‘head’ (H) or a ‘tail’ (T), and it is impossible to predict whether the result of a toss will be a ‘head’ or ‘tail’.

What is the meaning of Atmost one tail?

at most one tail means either we get 1 time tail out of n times or we get no tail i.e. all are heads. at least one head but at most one tail: if we are tossing a coin 5 times , at most one tail i.e. tail occurs either 1 time or it does not occur.

What is the probability of getting no tail?

So the probability of not getting a tail is 3/6.

What is the probability of getting tails 7 times?

1 in 128
With seven flips, we have 128 possibilities, with only one of these possibilities being a successful one (T-T-T-T-T-T-T). Thus, the probability of flipping seven tails in a row in seven flips is 1 in 128.

What is the probability of getting 1 head in 3 coin tosses?

0.88 is the probability of getting 1 Head in 3 tosses. Exactly 1 head in 3 Coin Flips The ratio of successful events A = 3 to total number of possible combinations of sample space S = 8 is the probability of 1 head in 3 coin tosses.

What is the probability of getting a tail on a coin?

As the toss of each coin is a unique event, then the probability of a tail is 50\% for each and every toss, regardless of the outcomes of the other two coins. Each individual toss is independent of all other tosses. To determine this you calculate the probability of failure to get 1 tail in other words 3 heads in a row.

What is the probability of only one tail in 3 tosses?

Therefore the probability of no tails in 3 tosses is 1 in 8 so the probability of at least 1 tail is the remainder or 7 out of 8 or 7/8. I’m embarrassed but did go back and checked my work.

What are the odds of getting 2 heads and a tail?

When you look at it, there are basically three ways to get 2 heads and a tail: HHT, HTH, THH. So, that give us our numerator: 3. Now, presuming that all three coins are fair, that means that each coin thrown has a 1/2 chance of going heads and a 1/2 chance of going tails.
