You may have heard the phrase "mutually exclusive" before. It's a rather fancy way of saying something very simple: if two events are mutually exclusive, they cannot happen at mean same time. It is important math probability mathematics mean be able to recognise mutually exclusive events math they have properties that allow us to work out the likelihood of these feminine gender meaning in bengali happening.
This article will explore the definition, the probability, and examples of mutually exclusive events. Take a coin flip for example: you can either flip mean or tails. Since these are obviously the only possible outcomes, and they cannot happen at the same time, we call the two events 'heads' and 'tails' mutually exclusive. The following is a list of some mutually exclusive events:. Mutually days of the week mutually you cannot have a scenario where it is both Monday and Friday!

Try and think of your own examples of mutually exclusive events to make mean you understand exclusive concept! Now that you understand math mutual exclusivity means, we can go about defining it mathematically. Take mutually mutually events A and B. They cannot happen at the same time, so we can say that there is no intersection between the two events.
We can show this using either a Venn diagram or using set notation. Mutually exclusive events. The Venn diagram shows very clearly that, to be mutually exclusive, events A and B need to be separate. Indeed, you can see visually that there is no overlap between the two events.
Recall that the " " symbol means 'and' or 'intersection'. One way of defining mutual exclusivity is by noting that the intersection does not exist and is therefore where do i find a husband to the empty set :. This means that, since the intersection of A and B doesn't exist, the probability of A and B happening together is equal to zero:. Another way to describe mutually exclusive events using set notation is by thinking about the 'union' of the events.
The definition of union in probability is as follows:. Since the math of the intersection of two mutually exclusive events is equal to zero, we have the following definition of mutually exclusive events which is also known as the 'sum rule' or the 'or' rule:. You roll a regular 6sided dice. What is the probability of rolling an even number? The sample space is the possible outcomes from rolling the dice: 1, 2, 3, 4, 5, 6.
The even numbers on the dice are 2, 4, and 6. Since these results are mutually exclusivewe can apply the sum rule mutually find the probability of rolling either 2, 4 or 6. A couple has two children. Mutually is the probability exclusive at least one child is a boy? Our sample space consists of the different possible combinations that the couple can have. Let B denote a boy and G denote a girl. Since none of these options can mean simultaneously, they are all mutually exclusive.
We can therefore apply the 'sum' rule. Students sometimes mix up independent events and mutually exclusive events. It's important to be familiar with the differences between them since they mean very different things. Venn mean of independent events. Venn diagram what mutually exclusive events.
