What is the probability that when a coin is flipped four times in a row it lands tails up every time?

What is the probability that when a coin is flipped four times in a row it lands tails up every time?

But with a fair coin, you have a 1/16 (6.25%) chance of getting tails 4 times in a row, and another 6.25% chance of getting heads 4 times in a row, which would be seen as equally remarkable.

How many possible outcomes are there if you toss a coin 4 times?

16 possible outcomes
Four Flips Suppose we flip a coin four times. Since each flip can come up heads or tails, there are 16 possible outcomes, tabulated below, grouped by the number of heads in the four flips.

What is the probability of flipping a coin 4 times and getting at least one tail?

Answer: Answer is 15/16.

What is the probability of flipping 5 heads in a row?

Your proposed answer of 13/32 is correct. If there are four or five heads in the sequence of five coin tosses, at least two heads must be consecutive.

When a fair coin is tossed 4 times there are 16 possible outcomes?

Complete step by step answer: We know that a coin can give heads or tails that is 2 outcomes. If it is tossed n times then it can give ${2^n}$ outcomes. Here it is being tossed 4 times it means it will give ${2^4} = 16$ outcomes. So, the total number of outcomes is 16.

What is the probability of flipping 2 heads in a row?

There is a 1/4 chance of getting two heads in a row when tossing a coin twice.

What is the probability of flipping at least one heads in three tries?

87.5%
Ben from St Peter’s followed the tree diagram and calculated out the answer: If you flip a coin three times the chance of getting at least one head is 87.5%.

How many different ways are there to get 3 heads in 10 flips of a coin?

So the probability of exactly 3 heads in 10 tosses is 1201024.

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

0.125
Answer: If you flip a coin 3 times the probability of getting 3 heads is 0.125.

What is the probability of getting exactly 5 heads in 10 coin flip?

63256
So, the number of ways of getting exactly 5 heads when 10 coins are tossed is 252. Now we need to find the probability of getting exactly 5 heads out of 10 tosses. So, the probability of getting exactly 5 heads when 10 coins are tossed is 63256. Hence answer is 63256.

What is the probability of flipping a coin 4 times?

Hence when a coin is flipped 4 times, there are 16 sample points in the sample space. What are the odds of a coin landing on heads 4 times? 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.

What’s the probability of flipping 4 heads in a row?

You want the probability of flipping at least four heads before obtaining the first tail. Thus you want the probability that at least the first four tosses are heads. This is 1 / 2 4. 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.

What’s the probability of getting four heads in a coin toss?

That assumes the coin is fair, has an equal chance of heads or tails. So the chance of getting a head in a coin toss is 0.5. As each toss is independent of others, the chance of flipping four heads is 1/2 x 1/2 x 1/2 x 1/2 or 1 in 16.

What’s the probability of getting 4 heads to start?

Getting 4 heads to start has probability ( 1 / 2) 4 = 1 / 16 as in the comment by @DonatPants. More formally, outcomes that satisfy your condition are HHHHT, HHHHHT, HHHHHHT, etc. So the total probability is the geometric series with probability A = ( 1 / 2) 5 + ( 1 / 2) 6 + ( 1 / 2) 7 + …. There is a formula for summing this series.
