let's think about flipping a coin and gettings lots of heads in a row.

What threshold would you use for deciding the coin was not fair? What probability of getting some number of heads in a row would you use to decide the coin was baised?

How many heads in a row would you need to get to reach your probability threshold?

I have a coin and I know that the probability p of flipping heads is either 1/2 or 1/4. I flip the coin 3 times and I get THT. Use the maximum likelihood method to determine the actual value of p.

- Your friend claims he has a fair coin; that is, the probability of flipping heads or tails is equal to 0.5. You believe the coin is weighted. Suppose a coin toss turns up 15 heads out of 20 trials. At α = 0.05, can we conclude that the coin is fair (i.e., the probability of flipping heads is 0.5)? You may use the traditional method or P-value method.

Coin toss experiment In this experiment, determine the number of heads and tails after flipping a coin for 1000 times. Use two different methods to find number of heads and tails Use for loops Use vectors in MATLAB. Repeat this experiment to find running average of flipping a coin for 200 and 2000 times. Plot the running average for two experiments using subplot functions

Consider flipping nn times a coin. The probability for heads is given by pp where pp is some parameter which can be chosen from the interval (0,1)(0,1). Write a Python code to simulate nn coin flips with heads probability pp and compute the running proportion of heads X¯nX¯n for nn running from 1 to 1,000 trials. Plot your results. Your plot should illustrate how the proportion of heads appears to converge to pp as nn approaches 1,000. In [ ]:...

A biased coin has probability p = 3/7 of flipping heads. In a certain game, one flips this coin repeatedly until flipping a total of four heads. (a) What is the probability a player finishes in no more than 10 flips? (b) If five players independently play this game, what is the probability that exactly two of them finish in no more than ten flips?
