Question 857805: sarwar has alot of time on his hands so he starts to toss a coin and count the number of times it comes up heads. he finds that out of 1000 tosses he gets heads 487 times and tails 513 times. a) calculate the experimental probability of getting heads when tossing the coin, b) explain whether or not you think the coin he was tossing was a fair coin c) sarwar notices a strange thing: his last eight tosses were all tails. if he were to toss it one more time do you think it would more likely come up heads or tails? Explain
Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! The probability of getting heads is 1 in 2. There are only two options.
In a sample size of 1000, the standard deviation is 15.811.
So, you would expect somewhere between 484 - 516 of the tosses to come up head (or tails). It is a fair coin.
If he tosses it again, it still has an even probability of coming up heads or tails. You've already established that it's a fair coin.
