i. Show that P(X = 4) = 1/3 , and draw up a table showing the probability distribution of X. [6] ii. Hence find the value of E(X) . [2] 5. A bus serving a number of villages is due to arrive in a particular village at 10 o'clock. Past experience tells the people waiting in the village for the bus that the probability of the service being cancelled on any day is 0.05, and that, when it runs, the probability of the bus being late is 0.1.

Descriptive Statistics Descriptive statistics involves organizing, summarizing and illustrating statistical data. The objective is to show important characteristics of the data without drawing any conclusions. Inferential statistics involves using a representative subset of data (a sample) in order to draw conclusions about unknown characteristics of an entire set of data (a population). Population: The entire

Topic : Probability Duration : 20 minutes [RJC/2010/Mid Year] In a given population, the proportion of people that are infected with the B3F1 virus is x. A test is conducted to determine whether a member of the population is infected. The medical test for the infection is not completely reliable: for someone infected with the B3F1 virus, there is a probability of 0.98 that the test will prove positive; whereas for someone not infected with the B3F1 virus, there is a probability of 0.01

large number In probability theory, the law of large numbers (LLN) is a theorem that describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer as more trials are performed. For example, a single roll of a six-sided die produces one of the numbers 1, 2, 3, 4, 5, or 6, each with equal probability. Therefore, the expected
