Question

You flip 10 fair coins. Amazingly, the first 9 flips all come up heads. What is the probability that the final flip will be a head too?

Answer 1

10 C 10 .5^10 * .5^0

Answer 2

The probability in this case is not conditional on what happened before. Therefore, the probability of heads is still 1/2.

Answer 3

50%, of course! It was completely chance that heads was flipped nine times in a row.

Answer 4

i spose it depends on how you decipher the question :)

Answer 5

What is the probability of getting 10 heads in a row? thats binomial

Whats the chance that given 9 heads you get another? 1/2

Answer 6

This would be exactly the same in the case of a die roll. Previous rolls have no impact on the next roll.
