You flip the same coin 900 mores times (1000 total flips). If half of the 900 additional flips are heads and half are tails, what is the empirical probability of getting a heads for this coin? (505 heads in 1000 flips)

Solutions

Expert Solution

Empirical probability getting a Head for this coin =Number of times Head occurred/ Total number of trials

                                                                       = 505/1000

                                                                      =0.505

So,

Answer is:

0.505

Suppose that I flip a coin repeatedly. After a certain number of flips, I tell you that less than 80% of my flips have been “heads”. I flip a few more times, and then tell you that now more than 80% of my (total) flips have been “heads”. Prove that there must have been a point where exactly 80% of my flips had been “heads”. (If we replace 80% with 40%, the statement is not true: if I flip “tails”...
