# How do you find the probability of two dependent events?

## How do you find the probability of two dependent events?

Use the specific multiplication rule formula. Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.

What are 2 examples of dependent events?

More formally, we say that when two events are dependent, the occurrence of one event influences the probability of another event. Simple examples of dependent events: Robbing a bank and going to jail. Not paying your power bill on time and having your power cut off.

What is an example of a dependent event in probability?

Dependent events in probability means events whose occurrence of one affect the probability of occurrence of the other. For example suppose a bag has 3 red and 6 green balls. Two balls are drawn from the bag one after the other.

### What does it mean for two events to be independent?

Two events are independent if the result of the second event is not affected by the result of the first event. If A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.

What are independent dependent events?

An independent event is an event in which the outcome isn’t affected by another event. A dependent event is affected by the outcome of a second event.

What does it mean if two events are dependent?

Two events are dependent if the outcome of the first event affects the outcome of the second event, so that the probability is changed. Example : The second draw is a dependent event.

#### Are two events independent?

In probability, we say two events are independent if knowing one event occurred doesn’t change the probability of the other event. For example, the probability that a fair coin shows “heads” after being flipped is 1 / 2 1/2 1/2 .

What does it mean for two events to be dependent?

Two events are dependent if the outcome of the first event affects the outcome of the second event, so that the probability is changed. Example : Suppose we have 5 blue marbles and 5 red marbles in a bag.

How are two dependent events related in math?

Dependent Events. Summary: Two events are dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed. The conditional probability of an event B in relationship to an event A is the probability that event B occurs given that event A has already occurred.

## Why are A and B dependent events in probability?

If the ball drawn in the first draw is not replaced back in the bag, then A and B are dependent events because P (B) is decreased or increased according to the first draw results as a red or green ball. Probability theory is an important concept that is quite familiar to the students who study mathematics in higher classes.

What does pitting mean in relation to dependent edema?

With dependent edema, pressing on the affected area can create dents. This characteristic is called pitting. If pressing on your skin doesn’t leave a pit or dent, you may have a different type of edema. What causes it? Gravity naturally pulls blood down toward your feet, or whichever part of your body is closest to the ground.

What does it mean when you have dependent edema?

With dependent edema, pressing on the affected area can create dents. This characteristic is called pitting. If pressing on your skin doesn’t leave a pit or dent, you may have a different type of edema.
