If a single die is rolled 6 times what is the probability of getting at least on 3?

You must first look at all possible outcomes:

1, 2, 3, 4, 5, 6

Then, reread the question that is being asked:

A dice is rolled 6 times, what is the probability of getting atleast a 3.

You should underline the important parts of the question and then preceed to answering:

When the question states, atleast a 3, it means to say the minimum result of 3 (as in 3, 4, 5 and 6)

The math:

(Outcomes that satisfy the statement)/(Total outcomes) * 100

We multiply by 100 to receive a percentage.

4/6 * 100 = 66.67%

The answer:

The probability of getting atleast a 3 when a dice is rolled 6 times is 66.67%.
