Four hundred twenty-five people were surveyed as they left the FSU-Virginia basketball game at the Tucker Center. The results were as follows: 205 attended the FSU-Marist game (M) 185 attended the FSU-Butler game (B) 185 attended the FSU-NC State game (NCS) 75 attended the Marist game and the NC State game 90 attended the NC State game and the Butler game 75 attended the Butler game and the Marist game 45 attended all three of the games Sketch a Venn diagram, save it as a pdf and attach your work. Then answer the questions below. How many attended only the FSU-Butler game? How many did not attend the Marist, Butler, or North Carolina State games? How many attended at least two of these games? How many attended the Marist and Butler games, but not the North Carolina State game? How many attended the North Carolina State or the Butler game
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.
