If you toss a die and it comes up with the number one 9 times in a row

Riddle: If you toss a die and it comes up with the number one 9 times in a row, what is the probability that it will come up with one on the next throw?

In this case since it is already given that the outcome of first 9 toss is one, and since each throw of the die is independent, the probability of getting a one in your next throw is same as probability of getting one in your first throw ( for independent events, the probability does not depend on probability of other events) that is one in six.

 

In short, it is always one in six as each roll is independent. That’s how simple the answer to this riddle is. Sometimes you do not have to think too much. The answer of this riddle is one in six.

Answer:  One in six. A die has no memory of what it last showed.
