Lets say you win a bar of chocolate if you end up in a red or a pink field. There is no number greater than 6 in the sample space S. For example the probability of flipping a coin and it being heads is ½ because there is 1 way of getting a head and the total number of possible outcomes is 2 a head or tail.
Well call this function p n where n is a natural number.
A mathematical expression can be as simple as 2 4 or as complex as -4xy 8x- 5xy. Basic Probability The probability for a given event can be thought of as the ratio of the number of ways that event can happen divided by the number of ways that any possible outcome could happen. This calculator evaluates arbitrary mathematical expressions. Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur or how likely it is that a proposition is true.
