What is the probability of flipping heads twice in a row?

So for one coin flip, The probability is 50\%. For getting heads twice, The probability is 25\%.

What is the probability of flipping a coin twice and getting exactly 2 tails?

You know from experience that if you flip a coin twice, sometimes you get tails twice in a row. That is because each time you flip the coin, the odds remain 1/2; the two flips are independent of each other. The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25\% of the time you’ll get heads twice in a row.

What is the probability of getting heads twice and tails twice in any order when tossing 4 coins?

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

What is the probability of obtaining heads exactly once?

In counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: HTTT, THTT, TTHT, or TTTH. Each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.

What is the probability of getting two head?

The probability of getting two heads in tossing a fair coin twice is therefore 1/4.

What is the probability of getting exactly one?

What is the probability of 2 tails on a coin toss?

See, the only possible outcomes with 2 tails are the following: You flip a coin 4 times, with 2 possibilities every flip, heads or tails. So, every time you throw there’s a 50\% chance you’ll throw tails. Now, we could make a sheet of every possible 4 flips, and determine how many of those have 2 tails as outcome.

What is the probability of a coin coming up heads twice?

When you flip a coin four times, what is the probability that it will come up heads exactly twice? Thus the probability is: 2 / 8 = 0.25 but the correct answer is 0.375. Can anyone explain why I’m wrong?

How many times can you flip a coin and get tails?

You flip a coin 4 times, with 2 possibilities every flip, heads or tails. So, every time you throw there’s a 50\% chance you’ll throw tails. Now, we could make a sheet of every possible 4 flips, and determine how many of those have 2 tails as outcome. That’d be a lot of work, so I’ll use some maths. There are sixteen possible outcomes.

What if my heads and Tails don’t have the same probability?

(Optional) If your heads and tails don’t have the same probability of happening, go into advanced mode, and set the right number in the new field. Remember that in classical probability, the likelihood cannot be smaller than 0 or larger than 1. The coin flip probability calculator will automatically calculate the chance for your event to happen.
