In relation to an evaluation of a natural park you have collected data on the visitors, and obtained data for the travel costs and their zones of origin, i.e. basic data needed when applying the Travel Cost Method. All visitors come by car and there’s only one person in each car. There are four different zones (I close, and IV most far away) and the total cost per person is given in the table below. Give a short explanation of the TCM. Would it be possible to do a reasonable TCM analysis from these data? Zone Travel cost per person ($) Total population in each zone Annual number of visitors from each zone I 10 4000 400 II 15 3000 250 III 20 3500 410 IV 25 4000 450
Addition Rule of Probability
It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.
Expected Value
When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known as the expectation, is denoted by: E(X).
Probability Distributions
Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosing a card. Each of these events has multiple possibilities. Every such possibility is measured with the help of probability. To be more precise, the probability is used for calculating the occurrence of events that may or may not happen. Probability does not give sure results. Unless the probability of any event is 1, the different outcomes may or may not happen in real life, regardless of how less or how more their probability is.
Basic Probability
The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the probability value 1 indicates that the event will occur. Sum of the probability value must be 1. The probability value is never a negative number. If it happens, then recheck the calculation.
