What are the odds of getting 5 heads in a row?
That probability is (1/2) * 5, or 1/32. Because there are two ways to get all five of one kind (all heads or all tails), multiply that by 2 to get 1/16. All of the other possibilities will result in at least one head and one tail, so the correct answer is 1 – 1/16 = 15/16.

What is head run probability?
A run is a sequence of more than one consecutive identical outcomes, also known as a clump. Let be the probability that a run of or more consecutive heads appears in independent tosses of a coin (i.e., Bernoulli trials).
What is the probability of 4 heads in a row?
1/16
Are heads more likely than tails?
The reason: the side with Lincoln’s head on it is a bit heavier than the flip side, causing the coin’s center of mass to lie slightly toward heads. The spinning coin tends to fall toward the heavier side more often, leading to a pronounced number of extra “tails” results when it finally comes to rest.
What is the probability of getting pure heads?
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
What is the probability of getting at least 3 heads?
Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. Since each of ht 4 flips has 2 possible outcomes (heads or tails), there are 24=16 outcomes in the sample space. At least 3 heads means 3 or 4 heads. (43)=4 ways to get 3 heads.
What is the probability of 3 heads in a row?
Three flips of a fair coin Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5%.
