Possible outcomes of one roll = 6.

Probability of an even number on one roll = 3/6 = 0.5 .

Probability of an even number on the second roll = 0.5 .

Probability of an even number on the third roll = 0.5 .

Probability of an even number on all three rolls = (0.5 x 0.5 x 0.5) = 0.125 = 1/8

The probability of at least one odd number is the probability of not getting

an even number on all 3 rolls. That's (1 - 1/8) = 7/8 or 0.875 or 87.5% .

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 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

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]


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.
