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

Probability of tossing a coin 8 times?

One hundred percent it you toss the coin eight times.


What's the probability of tossing a 6-sided die three times and getting an even number all three times?

Each time you toss the die the probability of rolling an even number is 3 out of 6 or 1/2. So, the probability of tossing three consecutive even numbers is (1/2)3 = 1/8 = 0.125, which is one chance in eight.



What is the probability of not drawing an ace or ten from a standard deck of 52 cards?

Probability that it is one of these eight cards is 8/52. Hence the probability of not getting these eight cards is 44/52


What is the probability of getting a card that is eight or lower in a deck of 52?

The probability is 61.538 if you are starting with a fresh deck and it is the first draw.


What is the probability of getting 2 tails if 3 fair coins are tossed?

There are eight possible outcomes: HHH, HHT, HTT, HTH, TTT, TTH, THH, THT. Of these, 3 contain two tails: HTT, TTH, and THT and the probability of getting two tails is 3/8. If the question were 'getting at least two tails' then TTT would need to be included for a probability of 4/8 or 0.5.


What is the probability of getting exactly seven tails if you flip a coin eight times?

The probability of getting exactly seven tails if you flip a coin eight times is: P(7T1H) = 8∙(1/2)8 =0.03125 ≈ 3.1%


10 coins are tossed once .The probalilty of getting exactly eight heads is?

The probability of getting 8 heads out of 10 tosses is (10C8)(1/2)^8 (1/2)^2 = 45 / 1024 = 0.0439. It is assumed that the probability of getting a head in a single toss is 1/2. 10C8 = 10 x 9 / 1 x 2 = 45



The probability of tossing three coins simultaneously and obtaining two heads and one tail is?

Looking at the total possibilities, you have eight different outcomes: TTT TTH THH HHH HHT HTT HTH THT Counting your two heads, one tails, you get a total of 3 possibilities out of 8, or 3/7



What are the probabilities of getting a sum o f7?

The experiment is undefined. On a single roll of eight or more normal dice the probability of getting a sum of 7 is 0.

The probability of rolling a four on an eight sided octahedron is 1 in 8, or 0.125.



If a coin is flipped and a die is rolled.what is the probability of getting heads and a 6?

The probability of flipping a heads is 1/2 and the probability of rolling a 6 is 1/6. By the laws of probability it would be logical to multiply them together, (1/2)(1/6) thus the answer being 1/12 with is roughly eight percent.

On an eight question true false quiz a student guesses each answer What is the probability that he gets at least One of the answers correct?

The probability of getting at least 1 answer correct = 1 - Probability of getting all answers correct.So in your case it for be P(at least 1 answer correct) = 1 - 1/256where 256 is your sample space, |S| = 2^8.


If a coin is tossed 3 times what is the probability of getting 2 and only 2 heads?

This is a problem concerning binomial probability distribution. If you have three coins, each one can land heads or tails. (We will ignore the remote chance that a coin will land on its edge.) Each coin has an equal probability of landing heads or tails. In other words, each coin has two possible states. Since there are three coins, there are 2 x 3 = 6 possible states. We can easily see what they are with a table: HHH HHT HTH HTT THH THT TTH TTT Three of those possible eight states contain two and only two heads. So the probability of throwing any of those three states is three in eight, or 3/8 = 0.375.


What are the odds of throwing an eight sided die and getting eight both times?

It you mean two 8 in a row then it's (1/8)2 = 1/64 as the probability to get 8 is 1/8

If two eight-sided dice are to be rolled On any roll what is the probability of getting two different numbers?

The first dice can show any of the eight numbers. If the dice are to show different numbers the second dice has 7 different numbers out of a possible 8 to chose from. So the probability is 7/8 or 0.875 or 87.5% chance.


A coin is flipped eight times What is the probability that the outcome will NOT be eight heads?

Probability of not 8 heads = 1- Prob of 8 heads. Prob of 8 heads = 0.5^8 = 0.003906 Prob of not 8 heads= 1- 0.003906 = 0.99604
