Oct 16, 2015 · 11/16 Consider a general task of flipping N coins and the probability of exactly K times the heads are up. Let's use a symbol P(N,K) for this probability. Knowing this, we can use the result to evaluate P(4,2)+P(4,3)+P(4,4) which will answer the question of what is the probability of getting heads at lease 2 times out of flipping a coin 4 times. I thought that all you have to do is: (1/3)(1/3)(2/3) It makes sense to me, but . math. a student claims that if a fair coin is tossed and comes up heads 5 times in a row, then according to the law of averages the probability of tails on the next toss is greater than the probability of heads. What is your reply? math

Suppose you toss a fair coin four times and observe the sequence of heads and tails. (a) Select a sample space. What values does the probability function P assign to each of the possible outcomes? (b) Suppose you record the number of heads from the four tosses.
Dec 01, 2010 · 5/16? sounds like there is too many smart those who fail to apply straightforward experience. the opportunities are 50/50. A coin has a 50% probability of touchdown on heads and a 50% of touchdown on tails each and each and every time it truly is flipped. it doesn't count number in case you've flipped and performance gotten heads ninety 9 situations, on the only centesimal turn, you ...
Jul 16, 2018 · The answer to this is always going to be 50/50, or ½, or 50%. Every flip of the coin has an “ independent probability “, meaning that the probability that the coin will come up heads or tails is only affected by the toss of the coin itself.
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.
Now if I ask you what is the probability of getting a Head when you toss a coin? Assuming the coin to be fair, you straight away answer 50% or ½. This is because you know that the outcome will either be head or tail, and both are equally likely. So we can conclude here: Number of possible outcomes = 2. Number of outcomes to get head = 1

  • A Coin Is Tossed 5 Times, Can You Find The Probability Of Getting At Least One Tail? Find The Probability Of Tossing At Least 2 Heads When A Fair Coin Is Tossed 10 Times.? What Is The Probability Of Getting 4 Heads, When The Coin Is Tossed 9 Times?
  • You toss a fair coin 4 times. What is the probability that (round to 4 decimal places) a) you get all Heads? b) you get at least one Tail? Points possible: 1 This is attempt 1 of 1 Submit

  • Probability Versus Physics. The coin toss is not about probability at all, he says. It is about physics, the coin, and how the “tosser” is actually throwing it. The majority of times, if a coin is heads-up when it is flipped, it will remain heads-up when it lands. Diaconis has even trained himself to flip a coin and make it come up heads 10 ...
  • Coin Toss Probability Calculator . When a coin is tossed, there lie two possible outcomes i.e head or tail. If two coins are flipped, it can be two heads, two tails, or a head and a tail. The number of possible outcomes gets greater with the increased number of coins. Most coins have probabilities that are nearly equal to 1/2.

You left something out there. 1 - (1/2)^7 = 1 - 1/128 or 127/128 NOT 1/128. Kids, always do a reality check. 1/128 is slim odds, but we know 7 tosses will almost guarantee at least one tail, so it should be fairly high odds.

1. Assume that you toss a fair coin 5 times. (a) What is the probability that you get 5 heads? (Show work and write the answer in simplest fraction form) (b) What is the probability of getting heads in the 5 th toss, given that the first four tosses are tails?
