### How do you find experimetal probability?

Experimental probability is calculated by taking the data
produced from a performed experiment and calculating probability
from that data. An example would be flipping a coin. The
theoretical probability of landing on heads is 50%, .5 or 1/2, as
is the theoretical probability of landing on tails. If during an
experiment, however, a coin is flipped 100 times and lands on heads
60 times and tails 40 times, the experimental probability for this
experiment for landing on heads is 60%, .6 or 6/10. The
experimental probability of landing on tails would be 40%, .4, or
6/10.

### What is the probability of flipping 25 heads in a row?

The best way to think about this is the following way:
What is the probability of flipping heads once?
1/2
What is the probability of flipping heads twice?
1/4 (1/2 * 1/2)
Using this we can derive the equation to find the probability of
flipping heads any number of times. 1/2n
Using this we plug in 25 for n and get
1/225 or as a decimal 2.98023224 x 10-8
or as odds 1:33,554,432

###### Asked in Probability

### What is the difference between mathematical probability and experimental probability?

Mathematical probability is how many times something is
projected to occur, where as experimental probability is how many
times it actually occurred.
For example, when discussing the probability of a coin landing
heads side up...
Mathematical probability is 1:2.
However, if you actually carryout an experiment flipping the
coin 5 times the Experimental probability may be 2:5

### What is the probability of flipping a coin twice and getting two heads?

The probability is 25%.
The probability of flipping a coin once and getting heads is
50%. In your example, you get heads twice -- over the course of 2
flips. So there are two 50% probabilities that you need to combine
to get the probability for getting two heads in two flips.
So turn 50% into a decimal --> 0.5
Multiply the two 50% probabilities together --> 0.5 x 0.5 =
0.25.
Therefore, 0.25 or 25% is the probability of flipping a coin
twice and getting heads both times.

###### Asked in Definitions, Probability

### What is the definition of experimental probability?

Experimental Probability: The number of times the outcome occurs
compared to the total number of trials.
example: number of favorable outcomes over total number of
trials.
Amelynn is flipping a coin. She finished the task one time, then
did it again. Here are her results: heads: three times and tails:
seven times. What is the experimental probability of the coin
landing on heads?
Answer: 3/10
Explanation: Amelynn flipped the coin a total of 10 times,
getting heads 3 times. Therefore, the answer is: 3/10.
