Question

On the average how many times must a dice be thrown until one gets a 6

Answer 1

Number of Outcomes when a dice is thrown = 6

and the set of Outcome = { 1 , 2 , 3 , 4 , 5 , 6 }

So, Chances of 6 to come as outcome = 1 as  { 6}.

So, Probability of coming 6 as an Outcome =

                                           Chances of  Outcome / Number of Outcome

Therefore , Probability = 1 / 6 .
