October 29, 2021.Tutorial on finding the probability of an event. In what follows, S is the sample space of the experiment in question and E is the event of interest. n(S) is the number of elements in the sample space S and n(E) is the number of elements in the event E. . Questions and their Solutions Question 1 A die is rolled, find the probability that an even number is obtained.

The probability of the student answering yes is 60% = 0.6. Let X be the number of students answering yes when 8 students are selected at random and asked the same question. The probability that X = 5 is given by the binomial probability formula as follows: P (X = 5) = 8 C 5 (0.6) 5 (1-0.6) 3 = 0.278691.

Statistically figuring sample size When designing a study, the sample size is an important consideration because the larger the sample size, the more data you have, and the more precise your results ... A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic. The statistic is an estimate of a population parameter.The lifespans of gorillas in a particular zoo are normally distributed.
