Question

Probability of getting atleast one 6 from rolling 3 dice

Answer 1

A dice has 6 sides.

Total number of possible outcome per dice = 6

Total number of "6" per dice = 1

Find the probably of getting a 6:

P(6) = 1/6

Find the probably of not getting a 6:

p(not 6) = 1 - 1/6 = 5/6

Find the probably of getting one 6 from the 3 dices:

P(at least one 6) = 1 - P(no 6 for all 3 times)

P(at least one 6) = 1 - (5/)(5/6)(5/6)

P(at least one 6) = 1 -125/216

P(at least one 6) = 91/216

Answer: The probability of getting at least one 6 is 91/216
