Explanation Given info: The emergency backup generators’ failure rate in a stadium is 22%. There are three backup generators in a stadium. Calculation: Here, the generators failure rate is 22% and the failure of three different generators are considered as independent. So, one event of getting a generator failure in the second selection is not affected by another event of getting generator failure in the first selection. Similarly, the ‘event of getting a generator failure in the third selection’ is not affected by another ‘event of getting generator failure in the first and second selections’. Then the probability for getting three independent generators’ failure is, P ( All three generators fail ) = P ( First generator fail and Second generator fail and Third generator fail ) = [ P ( First generator fail ) × P ( Second generator fail ) × P ( Third generator fail ) ] = 22 % × 22 % × 22 % = 22 100 × 22 100 × 22 100 = ( 0

Addition Rule of Probability

It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.

Expected Value

When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known …

Probability Distributions

Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosi…

Basic Probability

The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the prob…
