Probability is a mathematical measure of the likelihood that an event will occur. It is expressed as a number between 0 and 1, with 0 representing impossibility and 1 representing certainty.
The probability of a male smoker can be calculated by dividing the number of male smokers by the total number of males in the population. This can be represented as a fraction, decimal, or percentage.
There are several factors that can affect the probability of being a male smoker, such as age, socioeconomic status, cultural norms, and access to resources for quitting smoking.
No, probability cannot be used to predict individual outcomes. It is a measure of likelihood based on a large population, not a guarantee of what will happen to a specific individual.
Probability is a crucial component of scientific research. It allows scientists to make predictions and draw conclusions based on data, and helps to determine the significance of research findings. It also helps to identify patterns and relationships between variables in a study.
