Question

how do i find the probability of the occurance of at least one 6 in four throws of a die?

Answer 1

1 - probability of zero occurance of 6 in four throws

Answer 2

probability of zero occurance of 6 in four throws = (5/6)^4

Answer 3

4(1/6) does represent something.
It represents the probability of getting any of {1,2,3,6} out of one throw, something you probably learned a while back! :)
