Theoretical probability = 0.5

Experimental probability = 20% more = 0.6

In 50 tosses, that would imply 30 heads.

Formula for percent error?

Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100



What does a negative percent of the difference mean between experimental and theoretical probabilities of a given event?

First, it is important to note that it is very unlikely that the experimental and theoretical probabilities will agree exactly. As an extreme example, if you toss a coin an odd number of times, the resulting experimental probability cannot possibly be exactly 1/2. It should be easy to see that this remains true even if the coin is tossed googleplex+1 number of times.A negative difference could be because the number of trials was too small and, with an increased number of trials, the experimental probability would gradually increase towards the theoretical probability.It is also possible that the theoretical model is wrong. You may have assumed that the coin that was being tossed was fair when it was not. Or there were some factors that you failed to take full account of in your theoretical model.Or, of course, it could be a mixture of both.First, it is important to note that it is very unlikely that the experimental and theoretical probabilities will agree exactly.

How do you compute a percent error?

% error = |experimental value - theoretical value|/theoretical value * 100% It is the absolute value of the differe nce betwee n the experime ntal a nd theoretical values divided by the theoretical value multiplied by 100%.






What is the probability of 33.3 percent?

The probability of 33.3 percent is 0.333.


The probability for heart disease in a population is 30 percent the probability for the flu in the population is 50 percent the probability of getting both is 10 percent why or why not?

When determining the probability that two events happen at the same time, you convert the percents to decimals and then multiply the percents together. Therefore, 30 percent, or .3, times 50 percent, or .5 .3 x .5 = .15 Converting back into a percentage, the answer is 15% probability that you will get both. 10% is therefore incorrect.


What is a probability of 75 percent?

probability of 75 percent = 3/4


What would the theoretical probability be of flipping a coin four times?

Anyone can flip a coin four times so I say 100 percent probability. On the other maybe you should ask the odds of the results from four flips.


How do you show percent error?

Percent error = (actual value - theoretical value) / theoretical value * 100%


What is the probability of getting 75 percent on a four question quiz?

The answer depends on how well you do in the quiz: that is not a random experiment.


How do you find the percent of probability?

You multiply the probability by 100.


Probability of getting married and having children?

A man has an 81 percent chance to get married if they live the United States before the age of 40. A woman has an 86 percent chance of getting married.



The difference between the theoretical and empirical probability?

The term empirical means "based on observation or experiment." An empirical probability is generally, but not always, given with a number indicating the possible percent error (e.g. 80+/-3%). A theoretical probability, however, is one that is calculatedbased on theory, i.e., without running any experiments.Since there is no theory that will calculate the probability that an area will experience an earthquake within a given time frame, the 90% figure is an empirical probability, presumably based on data of major earthquakes in the San Francisco area over past years.


Explain how using a spinner would help find the experimental probability that a soccer player who makes 75 percent of his penalty kicks will score a goal on a penalty kick?

Get the spinner and have 4 sections, 3 with score and 1 with miss. Whichever one it lands on is the outcome. However, this is only purely theoretical as football/ soccer is played on grass and not with a spinner.


What is the percent error calculation used to determine?

When you calculate results that are aiming for known values, the percent error formula is useful tool for determining the precision of your calculations. The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value.


A bag has 13 green marbles What is the probability pf drawing out a green marble?

your probability would be 13/13. you would have a 100 percent chance of getting a green marble

Probability of rain on monday is what is the probability of no rain on Monday?

IF probability of rain is X percent then probability of no rain is 100- X percent. For example if prob of rain is 80% prob of no rain is 20%


What is the percent error formula for mass of pennies?

For any percent error formula: 100 x (Experimental Value - Theoretical Value) / Theoretical Value Take the absolute value of this (make it positive) , and give it a percent sign. Example: The listed mass was 1 gram, and you found it to be .9 grams 100(0.9-1)= -10 -10/1 =-10 -10 becomes 10 10% error You will NEVER have a negative percent error, and its a good idea to write "error" after the percent sign.
