How do you solve independent events?
Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true. You can use the equation to check if events are independent; multiply the probabilities of the two events together to see if they equal the probability of them both happening together.
What makes events independent dependent give an example of each?
When two events are said to be independent of each other, what this means is that the probability that one event occurs in no way affects the probability of the other event occurring. An example of two independent events is as follows; say you rolled a die and flipped a coin.
What is the difference between dependent and independent event?
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’s the difference between a dependent and independent student?
If you’re a dependent student, you will report your and your parents’ information. If you’re an independent student, you will report your own information (and, if you’re married, your spouse’s).
What is the similarities of independent and dependent variable?
These two variables are used alongside each other, and a change in the independent variable will translate to a change in the dependent variable. That is, they are similar in the sense that they change at the same time. These changes may, however, occur in the opposite direction to each other.
Can variables be both independent and dependent?
No. The value of a dependent variable depends on an independent variable, so a variable cannot be both independent and dependent at the same time. It must be either the cause or the effect, not both!
What are examples of independent?
The definition of independent is someone or something that is free from the influence or control of another. An example of independent is someone who lives on their own and supports themself. Free from the influence, guidance, or control of another or others; self-reliant.
Is blood pressure a dependent or independent variable?
The independent variable in the study is the type of pill the patient is given (placebo or Brackenolol). The experimenter determines whether a patient receives the placebo or Brackenolol. Thus, the dependent variable in the study is the measure of blood pressure.
Is pressure independent of temperature?
For example, temperature and specific volume are always independent. However, temperature and pressure are independent only for a single-phase system; for a multiphase system (such as a mixture of gas and liquid) this is not the case. (e.g., boiling point (temperature) depends on elevation (ambient pressure)).
Is temperature or pressure the independent variable?
Boyle’s Law. Gases are often characterized by their volume, temperature, and pressure. These characteristics, however, are not independent of each other. Gas pressure is dependent on the force exerted by the molecular collisions and the area over which the force is exerted.
What is the dependent variable in Boyle’s law experiment?
BOYLE’S LAW. – he wanted to investigate the relationship between pressure and volume. ▪ independent variable = pressure. ▪ dependent variable = volume. ▪ controlled variables = temperature and number of moles (no gas enters.
What is the independent variable in Boyle’s law experiment?
What happens to the volume as the pressure decreases? Plot your results as a graph of pressure versus volume (in other words plot pressure on the x-axis and volume on the y-axis). Pressure is the independent variable, which we are changing to see what happens to volume.
Is Boyle’s Law direct or inverse?
The law itself can be stated as follows: For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle’s law is a gas law, stating that the pressure and volume of a gas have an inverse relationship.
Is P and V directly proportional?
Boyle’s law states that pressure (P) and volume (V) are inversely proportional. Charles’ law states that volume (V) and temperature (T) are directly proportional. Gay-Lussac’s law states that pressure (P) and temperature (T) are directly proportional.
