Q: If you have an 80% chance of succeeding, how likely are you to fail 4 times in a row? The chance of failure on the each try is 20% or 0.20, and chances of sequential events are multiplied together so therefore the chance of failure four times in a row is…
Carolyn found a correlation of .80 between lecture attendance and exam performance. She should conclude that... a. doing the exam is a very good idea b. attending lectures is a very good idea c. it doesn't really matter if you attend lectures or not d. if you attend the lectures, the chances are you will get at least 80% in the exam
Let’s say that “A” means success. If both 33% chances need to succeed, then we can see that “A A” (Column 1) happens once out of nine times, so you’d have an 11% chance. But if you’re getting a second 33% chance, then you have a 33% chance in the first row (Columns 1–3).

23 people. In a room of just 23 people there's a 50-50 chance of at least two people having the same birthday. In a room of 75 there's a 99.9% chance of at least two people matching.
In a study on recall after listening to a seminar, students forgot more than 90% of the points from the lecture after 14 days.
If you want to produce results that are representative of the whole population, probability sampling techniques are the most valid choice. There are four main types of probability sample....There are four main types of probability sample.Simple random sampling. ... Systematic sampling. ... Stratified sampling. ... Cluster sampling.
Probability sampling refers to the selection of a sample from a population, when this selection is based on the principle of randomization, that is, random selection or chance. Probability sampling is more complex, more time-consuming and usually more costly than non-probability sampling.
Studies show that people remember: 10% of they hear — — 20% of what they read — — 80% of what they see. And this is because the human brain process visual cues better rather than the written language.
In a recent study at the University of Toronto, such experts were asked to predict the accuracy of memories of events that happened two days earlier. While recollections of these events were very good—more than 90 percent correct on average—the experts predicted they would be only 40 percent correct.
Here, P (X) represents the probability of the event X. Thus we can write: P (X) = n/N; where 'n' is the number of the favourable outcomes and 'N' is the number of total possible outcomes.
Formula to Calculate Probability The formula of the probability of an event is: Probability Formula. Or, P(A) = n(A)/n(S)
There are five types of sampling: Random, Systematic, Convenience, Cluster, and Stratified.
The quantitative research sampling method is the process of selecting representable units from a large population. Quantitative research refers to the analysis wherein mathematical, statistical, or computational method is used for studying the measurable or quantifiable dataset.
Sampling helps a lot in research. It is one of the most important factors which determines the accuracy of your research/survey result. If anything goes wrong with your sample then it will be directly reflected in the final result.
