Concept explainers

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…

What's the probability that the member selected at random is from the shaded area

**Pregnancy Length in a Population of New Mothers** This image shows a normal distribution curve representing the pregnancy length in days for a population of new mothers. - **Mean (μ):** 269 days - **Standard Deviation (σ):** 11 days The graph illustrates a range between 281 and 294 days, highlighted in a teal-shaded area, indicating the subset of the population that falls within this range. The x-axis represents the pregnancy length in days, starting from 239 days, while the y-axis details the frequency of occurrences. The shaded area highlights the probability of pregnancy lengths between 281 and 294 days.
