A dice is thrown 80 times. it lands on a six 12 times. What is the probability of throwing a six?
Question asked by: knowitall
The way probability works is:
The number of possible outcomes
The number of total outcomes
Therefore, probability of roling a 6, based on previous events is:
P = 12/80
Which rounds down to 3/20.
So the probability of roling a 6 from using previous events is 3/20ths!

I feel the probability is 12/(6 to the power 80) coz
every time you throw a dice the sample space gets multiplied.

Wrong, if you already throw the dice, the probability doesn't matter on past throwings. It will be 1/6.
If your anwswer were correct, people should use new dices everytime they want to play or chances could be 'adjusted'.

The probability of throwing a 6 after it lands 12 times in the previous throws is still 1/6, the same as it always is.
