How many times would a coin have to show heads in 50 tosses to show an experimental probability of 20 percent more than the theoretical probability of getting heads?

Theoretical probability = 0.5
Experimental probability = 20% more = 0.6
In 50 tosses, that would imply 30 heads.

What is a probability of 75 percent?
probability of 75 percent = 3/4
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.
What would be the experimental probability of rolling a die 50 times and getting 4?
The experimental probability can't be predicted. If it could, then there wouldn't be any reason to do experiments. The probability of rolling a die 50 times depends on how passionately you want to see what's going to happen if you do. There are six different ways a single die can come up on each roll. So the probability of rolling any particular number between 1 and 6 on each roll is 1/6 or (16 and 2/3) percent. If it isn't, then the die isn't a fair die. The die has no memory, so the probability of any particular number is the same on every roll, even if the same number has or hasn't come up on the previous 100 or 1,000 consecutive rolls. If the probability of any outcome depends on what has come before, then the laws of probability aren't operating, and it's not an honest game.
What is the probability of getting a tail if a coin tossed once?
Since the coin only has two sides, the probability of getting either heads or tails in any one toss is 1 in 2, or 50%. 50 precent chance. Everytime you toss it, 50 percent.
Can probability be written as percent?
Yes.
Formula for percent error?
Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100
Would the experimental percent oxygen be higher or lower than the theoretical percent oxygen?
because of variable in the situation '
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.

Is experimental yield the same as percent yield or actual yield?
The percentage yield is the Actual Yield divided by the Theoretical Yield, all multiplied by 100. Percentage = [(Actual)/(Theoretical)] x 100
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 if a potassium chlorate sample is contaminated with KCL would the experimental percent oxygen be higher or lower than the theoretical percent oxygen?
the experimental % oxygen would be lower because there would be more KCL in the simple than oxygen
Identify the following probability as theoretical or empirical In a wooded area you randomly select 10 trees and find that 5 are tagged You conclude that there is a 50 percent probability of rando?
Empirical
What is the probability of getting 1 right answer out of 2 questions if the favorable outcome is 40 percent?
The probability is 0.48
How do you find the probability on a biased coin of getting 3 heads out of 3 coin tosses when the probability of getting a head is 60 percent?
0.63 = 0.216
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.
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 the probability of 33.3 percent?
The probability of 33.3 percent is 0.333.
