Respuesta :
It's a conditional probability
P( getting a given number AND getting again the same number)
P(of getting any number) =1/6
P(of getting once again the same number) 1/6 x 1/6 = 1/36
P( getting a given number AND getting again the same number)
P(of getting any number) =1/6
P(of getting once again the same number) 1/6 x 1/6 = 1/36
Since these probabilities are independent of each other you would mulitiply the individual probabilities.
First Roll: P(1) = 1/6
Second Roll: P(1) = 1/6
(1/6) * (1/6) = 1/36
First Roll: P(1) = 1/6
Second Roll: P(1) = 1/6
(1/6) * (1/6) = 1/36
