Explanation Given: Assume that for any given line human birth, the chances that a child is a boy or a girl are equally likely. Approach: The formula for getting exactly r successes in n independent trials is P ( X = r ) = C ( n , r ) p r ( 1 − p ) n − r … ( 1 ) Here, X is a random variable. The formula for the complement of event E is P ( E ′ ) = 1 − P ( E ) … ( 2 ) Here, E ′ denotes the complement of E . Calculation: Let X be the event that the child is a boy To determine (b) To find: The probability that two or more seeds will germinate

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…
