What is the probability of getting both tails on two tosses of a coin?
The probability of two tails on two tosses of a coin is 0.52, or 0.25.
What is one method for calculating the total number of outcomes in a sample space?
You think of each toss as having heads or tails, so there are two choices. If you toss the coin twice you have 4 choices HH, TT, HT and TH. The number of different coin tosses is 2^n ordered tosses and n+1 unordered. For example in two tosses, 2^2=4 ordered tosses if HT is different than TH and if HT is the same as TH then we have 2+1=3 different possible tosses.
How does increasing the number of tosses of a coin affect the average size of the deviation?
It's an important principle or probability. The more coin tosses there are, the more chance there is for an expected outcome.
What is the probability of of tossing heads on the first 6 tosses of a fair coin?
The probability of tossing heads on all of the first six tosses of a fair coin is 0.56, or 0.015625. The probability of tossing heads on at least one of the first six tosses of a fair coin is 1 - 0.56, or 0.984375.
What is the probability of getting zero tails on a two tosses?
0.5
What is the probability of getting 2 heads on all 3 tosses?
The probability is 0, since there will be some 3-tosses in which you get 0, 1 or 3 heads. So not all 3-tosses will give 2 heads.
What does flings mean?
Throws, Tosses.
What is the probability of getting both tails on two tosses of a coin?
The probability of two tails on two tosses of a coin is 0.52, or 0.25.
What is the probabiltiy that a coin will land on heads in six tosses?
The probability that a coin will land on heads - at least once - in six tosses is 0.9844
What is the frequency for heads in a series of 100 tosses of a fair coin?
The theoretical frequency of heads will be .5 and as you do more and more coin tosses the observed frequency should get closer and closer to .5. With 100 tosses, it will be pretty close, but not exactly .5
What are the chances of a coin landing on heads 35 times in a row?
In 34 or fewer tosses, the answer is 0. In infinitely many tosses, the answer is 1. The answer depends on the number of tosses and, since you have chosen not to share that critical bit of information, i is not possible to give a more useful answer.

Find the probability of heads on three consecutive tosses of a coin?
The number of total outcomes on 3 tosses for a coin is 2 3, or 8. Since only 1 outcome is H, H, H, the probability of heads on three consecutive tosses of a coin is 1/8.

It's an important principle or probability. The more coin tosses there are, the more chance there is for an expected outcome.

What is the total number of outcomes for this event if Alan tosses a six sided number cube?
The total number of outcomes if Alan tosses the cube is 1 since he only tosses the cube once. However, Alan could roll a 1, 2, 3, 4, 5, or 6.
When you Toss a coin 3 times and what is the probability of getting at least one head?
Pr(At least one head in 3 tosses) = 1 - Pr(No heads in 3 tosses) = 1 - Pr(3 tails in three tosses) = 1 - [Pr(T)*Pr(T)*Pr(T)] since the three tosses are independent. = 1 - 1/2 * 1/2 *1/2 = 1 - 1/8 = 7/8
