Probability-Range, Addition, Multiplication & Conditional: Inferential Statistics|Part 4 of 4

Dr. Manishika Jain in this lecture explains Probability - Range, Addition, Multiplication & Conditional: Inferential Statistics | Part 4 of 4 Probability - expected relative frequency of an outcome; the proportion of successful outcomes to all outcomes. Outcome - term used in discussing probability for the result of an experiment (or almost any event, such as a coin coming up heads or it raining tomorrow). Frequency is how many times something happens The relative frequency is the number of times something happens relative to the number of times it could have happened; that is, relative frequency is the proportion of times something happens. (A coin might come up heads 8 times out of 12 flips, for a relative frequency .) Expected relative frequency is what you expect to get in the long run if you repeat the experiment many times. (In the case of a coin, in the long run you would expect to get 1/2 heads). This is called the long run relative-frequency interpretation of probability. We also use probability to express how certain we are that a particular thing will happen. This is called the subjective interpretation of probability. Suppose that you say there is a 95% chance that your favorite restaurant will be open tonight. Toss – chance of head or tail is 50% In a class has 200 people in it, and 30 are seniors. If you were to pick someone from the class at random, the probability of picking a senior would be 30/200, or 0.15. This is because there are 30 possible successful outcomes (getting a senior) out of 20 possible outcomes Complete Online Intensive Learning Course - https://www.doorsteptutor.com/Exams/U...
