The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

The chance of all of two or more events occurring is called the intersection of events. For independent events, the probability of the intersection of two or more events is the product of the probabilities.

I would define standard deviation as a measure of how dispersed the data is in relation to the mean. For example, low standard deviation means the data is clustered around the mean while if the deviation is high it tells you that the data is more spread out.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score.

The chance of all of two or more events occurring is called the intersection of events. For independent events, the probability of the intersection of two or more events is the product of the probabilities. In the case of two coin flips, for example, the probability of observing two heads is 1/2*1/2 = 1/4.
