A coin is tossed two times what is the probability of obtaining at least one tail?

3/4 The only way a tail doesn't show up is if all heads come up. P(all heads) = (1/2)*(1/2)=1/4 P(at least one tail)=1-P(all heads)=1-(1/4)=3/4


A dime is toss three time probability that it will come up head all three times is .125?

Yes, if it is a fair coin.


Will a win lottery numbers will come up again?

The probability of a certain set of numbers coming up in the lottery is equal to the probability of any other set of numbers coming up. Just because a certain set of numbers came up, that does not mean that the same set of numbers is more or less likely to come up again.


Rolling three dice what is the probability of rolling an odd number?

The probability that, when rolling three dice none will come up odd is broken down by the probability that on odd roll will occur as an independent event. Rolling the first die has a probability of 3/6 that it will be odd. Rolling the second has the probability of 3/6 that it will be odd. Rolling the third has a probability of 3/6 will be odd. Rolling three and coming up with odd is really the probability that no odd numbers occurred, so therefore an even number DID happen (3/6), and an even number DID happen (3/6), and an even number DID happen (3/6). That's really just 1 - (3/6^3) or simplified 1 - (1/2^3). So therefore the probability that an odd number occurred in 3 die rolls is about 87.5%.


What is the probability of rolling a 6-sided dice and getting an odd number three times and a row?

The cube has 6 faces, so it can come up in 6 different ways.Three of the possible outcomes are odd numbers. (1, 3, and 5)Probability of an odd number on the first roll = 3/6 = 1/2 .Probability of an odd number on the second roll = 3/6 = 1/2 .Probability of an odd number on the third roll = 3/6 = 1/2 .Probability of an odd number on all 3 rolls = (1/2) x (1/2) x (1/2) = 1/8 = 0.125 = 12.5%

If You flip 9 fair coins Amazingly the first 8 flips all come up heads What is the probability that the final flip will be a head too?

1/2 apex It does not matter what each prior flip's result was. Each flip has a probability of 0.5 heads or tails. Coins do not have "memory".


What is the probability that a single coin flip will come up heads?

The probability that a single coin flip will come up heads is 0.5.


What is the probability of tossing seven coins at one time and having 7 of them come up heads?

The probability would be once in 128 attempts. You don't have to toss seven coins simultaneously. the 7 tosses just have to be independent of one another.


What is the probability of getting two heads one tail when you spin 3 coins?

First work out the probability of the first two coins being heads and then the last being tails. This is 1/2 x 1/2 x 1/2 which is 1/8 The next step is to find out how many different orders the coins can come in. In this case there are 3 possible orders (HHT, HTH, and THH). Multiply this by the above probability and you get 3/8. Therefore the probability of getting two heads and one tail is 3/8


What is the probability that the next coin flip will come up heads?

If it is a fair coin then the probability is 0.5


What is the probability that 3 heads come up on a throw of 3 dice?

The probability is very, very small, because there are no heads marked anywhere on the dice.


What is the probability that a single coin flip will come up heads on the first two flips?

The probability of heads on the first flip is 50%.The probability of heads on the second flip is 50%.The probability of both is (50% x 50%) = 25% .=========================================Another way to look at it:Two tosses can come up in four different ways:H HH TT HT TOnly one of these . . . H H . . . counts as success.1 out of 4 = 25% .


What is the probability of getting 2 heads when you toss three coins?

If you mean 'at least' 2 heads, the probability is 50%. If you mean exactly 2, the probability is 3/8, or 37.5%. There are 3 independent coin tosses, each of which is equally likely to come up heads or tails. That's a total of 2 * 2 * 2 or 8 possible outcomes (HHH, HHT, HTH, etc.). Of these, 4 include 2 or 3 heads, which is half of 8. Only 3 include exactly 2 heads, so the probability of that is 3/8.


Two events in which eitherone or the outher must take place but they can't both happen at the same time The probability is 1?

This is correct. For example the probability of tossing a coin so that it comes up heads is 1/2 and the probability that it comes up tails is also 1/2. The probability that it will come up either heads or tails is 1.
