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%.

If a die is rolled 3 times what is probability of getting an even number?
The probability of getting an even number on at least one of the 3 rolls is 7/8.
A pair of dice are rolled find the probability at least one dice is a 4?
When rolling one die, the probability of getting a 4 is 1 in 6, or 0.1667. If two dice are rolled, you get two unrelated chances of rolling at least one 4, so the probability is 2 in 6, or 0.3333.
What is the probability of flipping a head when you roll a coin 3 times?
If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8
If you were to flip a coin 4 times what is the probability of getting heads at least one time?
As the question is "what is the probability of getting at least one head" the correct way to answer this is to ask what is the probability of not getting any heads and then subtract this from 1.The probability of not getting a head in 4 flips = 0.54 (i.e. 0.5 * 0.5 * 0.5 * 0.5) = 1/16.Therefore the probability of getting at least one head is 1 - 1/16 = 15/16.
What is the probability of getting a least one tail when tossing eight fair coins?
The probability of getting at least 1 tails is (1 - probability of getting all heads) The probability of getting all heads (no tails) is ½ x ½ x ½ x ½ x ½ x ½ x ½ x ½ = 1/256 = 0.00390625 so the probability of getting at least ONE tails is 1-0.30390625 = 0.99609375 = 255/256

If a number cube is rolled 4 times what is the probability that the same number is rolled at least twice?
It is 0.722... recurring.
A dice is rolled 12 times What is the probability of at least two 5's appearing?
The probability is 0.6187, approx.
If sixteen dice are rolled what is the probability of rolling at least one six?
It is 0.9459
If 3 dice were rolled 1000 times what is the probability of rolling a 14?
The probability that 14 is rolled at least once is 1 - 5.5*10-32 which, for all intents and purposes, can be treated as 1.
If you roll two dice what are the odds that you get a one or a five?
I suppose you mean, at least one of those numbers. Just calculate the probability of NOT getting any of those, and take the complement. The probability of not getting a one nor a five on a single die is 4/6 or 2/3. For two dice, the probability is 2/3 x 2/3 = 4/9. So, the probability of getting at least a one or a five with two dice is 1 - 4/9 = 5/9.I suppose you mean, at least one of those numbers.

What is the probability of rolling a six-sided dice twice and coming up with at least one number 5?
First calculate the probability of NOT getting a single 5. This probability is 5/6 x 5/6 = 25/36. Therefore, the probability of getting at least one 5 is the complement thereof, that is, 1 - 25/36 = 11/36.

What is the probability of getting at least one prime number in two dice?
The probability of getting at least one prime number in two dice is 3/4.
What is the probability of rolling at least two sixes when a fair six sided die is rolled 5 times?
It is 0.1962
What is the probability that a six is rolled exactly once if it is known that at least one six is rolled?
The answer depends on how many rolls. If there were n rolls, then the probability is n*(1/6)*(5/6)n-1/[1 - (5/6)n]
