Here are various terms that are utilized in the probability and statistics concepts.: 1. Random Experiment:An experiment whose result we cannot predict until and unless it is noticed is known as a random experiment. The most basic example can be throwing a dice randomly. It is certain that the result will be uncertain t See more The term probability refers to the likelihood of an event occurring. You can calculate an event's probability with the following formula: For example, if you wanted to see how likely it would be for a coin to land heads-up, you'd put it into the formula like The probability of the student answering yes is 60% = 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 () 5 () 3 = b) P (X ≥ 6) = P (X = 6 or X = 7 or X = 8) Example 4: Find the mean of the following data: 55, 36, 95, 73, 60, 42, 25, 78, 75, Solution: Given, 55 36 95 73 60 42 25 78 75 Sum of observations = 55 + 36 + 95 + 73 + 60 + 42 + 25 + 78 + 75 + 62 = Number of observations = Mean = /10 = Example 5: Find the median and mode of the following marks (out of 10) obtained by 20 students WebLet's take a look at a few examples of probability.
