Explanation Given Information: A bag contains 5 yellow marbles, 4 white marbles, 3 blue marbles and 7 red marbles. Formula used: If the probability of one event does not affect the probability of other event then the two events are called Independent. If two events A and B are independent then they can be expressed mathematically as shown below: p ( A and B ) = p ( A ) ⋅ p ( B ) Calculation: Consider a bag containing 5 yellow marbles, 4 white marbles, 3 blue marbles and 7 red marbles. Total number of marbles 5 + 4 + 3 + 7 = 19 Number of red marbles: 7 Event A: drawing a red marble p ( r e d ) = 7 19 Now, the marble is replaced in the bag. Total number of marbles 5 + 4 + 3 + 7 = 19 Number of white marbles: 4 Event B: drawing a white marble p ( w h i t e ) = 4 19 Now, the marble is replaced in the bag

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…
