Right. Winning AT LEAST once out of 100 tries is equal to NOT(NEVER winning in one of 100 tries). The one in the brackets is 0.99 ^100, which is about 0.33. Taking the NOT is subtracting that result from one, yielding about 0.63396766. To get a percentage multiply this by 100.

It means that the probability is calculated (or more precisely, estimated) based on experiment. For example, if a certain event occurs 70 times in 1000 tries, you can estimate the probability to be approximately 7%.

### I need help....does this guy like me?

If a guy is always looking at you but looks away when you look at him, if he smiles at you constantly, if he tries to be close to you, or even tries to pass by you and maybe touches your arms a little. The probability is he likes you.

### What should occur in a probability experiment?

An event, unless it already had been occured and the experiment tries to resolve posterior probabilities on the event

### How are ratio and probability the same?

A ratio is a comparison of the relative size of two different things. Probability is the change that something will (or will not) occur. Probability can be expressed as a ratio of Yes to No (or, "will occur" to "won't occur"). That is, Probability is the relative size of Yes to No. So, if something is said to have a 60% Probability of occurring, what that is indicating is that, out of 100 tries, 60 will be the outcome indicated. While probability is usually expressed as a percentage, it is entirely possible to express it as a ratio. In the aforementioned example, a 60% Probability of occurrence could also be said to be a 60:40 (or, reduced, 3:2) ratio in favor of happening.

### Will someone please explain probablilityto you?

Probability, simply put, is the likelihood that something will occur. The easiest way to explain probability to someone is to use a hypothetical situation. For example, if a person whose usual size of jeans is 8 tries on a pair of size 8 jeans, the probability that they will fit is high. However, since sizes vary from one manufacturer to another, it is a probability rather than a certainty.
