In this definition 'large number' is vague and will not be made precise here. The following links use the Virtual Laboratories in Probability and Statistics by Professor Kyle Siegrist of the University of Alabama at Huntsville. Each link opens a page that illustrates the relative frequency definition of probability for a different situation.
Sample Space Definition of Probability
Which is more likely 9 heads in 10 tosses of a fair coin or 18 heads in 20 tosses show your work?The probability of success (p) that is getting a head is 0.5 as it is a fair coin. Therefore, the probability of 18 heads in 20 tosses of a fair coin is 0.0002. Therefore, it can be concluded that 9 heads in 10 tosses of a fair coin is more likely than 18 heads in 20 tosses of a fair coin.
What is the probability of tossing a fair coin 10 times and getting heads 9 times?Geoff K. The probability is approximately 20.51%.
What is the probability of getting 10 heads in 20 flips?If the coin is fair, then the probability of getting either a head or a tail is 0.5. So the probability of getting 10 heads in a row is 0.510≈0.00098 which is 1 in 1024.
Which of the following is more likely when tossing a fair coin?Answer and Explanation: We can see that the there are more chances of tossing 8 heads in 10 tosses than tossing 80 heads in 100 tosses.
