What else can I help you with?
Identify the following probability as theoretical or empirical. After tossing the same coin 10 times you are surprised to find that tails has come up 8 times. You therefore conclude that this coin is?

How do you find the probability density function?
The probability density function of a random variable can be either chosen from a group of widely used probability density functions (e.g.: normal, uniform, exponential), based on theoretical arguments, or estimated from the data (if you are observing data generated by a specific density function). More material on density functions can be found by following the links below.
How would you compare theoretical probability and experimental probability for getting three heads to the theoretical probability. would you expect the probabilities to be equal .?
I'm going to assume you're looking for the probability of getting three heads out of three coin spins and that you're using a fair coin. For coin spins, theoretical probability is very simple. The probability of getting three heads in a row is 1/2 * 1/2 * 1/2 = 1/8. This means that if you tossed a coin three times, you'd expect to see three heads once every 8 trials. For experimental probability you need to define clear trials, for this experiment you can't just spin a coin over and over and count the number of times you see three heads in a row, for example, if you threw the following: H T H H T T H H H H H T T H T T T you have three cases where you have three heads in a row, but they all overlap so these are not independent trials and cannot be compared to the theoretical result. When conducting your experiment, you know that if you get a T in your trial, it doesn't matter what comes after, that trial has already failed to get three heads in a row. The trial is deemed a success if you get three heads in a row, naturally. As a result, if you threw the above sequence, you would to determine your experimental probability in the following way: H T fail H H T fail T fail H H H success H H T fail T fail H T fail T fail T fail In this example we have 8 trials and one success, therefore the experimental probability is 1/8. The sample variance (look it up), however is also 1/8, meaning that all you really know is that the experimental probability could be anywhere between 0 and 1/4. The only way to get the variance down (and therefore reduce your confidence interval) is to perform more and more trials. It's unlikely for the theoretical probability and experimental probability to be EXACTLY the same but the more trials you do, the more the experimental probability will converge on the theoretical probability.
Which of the following cannot be the probability of an event?
There is insufficient information in the question to properly answer it. You did not provide the list of "the following". Please restate the question. However, by definition of probability, a probability less than 0 (the event will never happen) or greater than 1 (the event will always happen) is impossible, so maybe that answers your question.
What of the following numbers could not be a probability explain. 13 0 89 1 54?
They are 13, 89 and 54 because probability is on a scale of from 1 to to 0

When is y a constanant?
The Y is a consonant for its general pronunciation, which is when Y starts a word, the Y starts a syllable or the following letter of Y is a vowel. If the Y ends a word, it's somewhere inside a syllable or inside a syllable intervention, especially without a surrounding vowel in one syllable like "byte", or if the following letter of Y is a consonant, then that's when Y becomes a vowel. If the following letter is a consonant, the reason why Y would become a vowel is because Y can't be a consonant blend. However, Y is not a vowel for its general pronunciation nor in the phonetic alphabets.
