WebbThe empirical rule in statistics, also known as the 68 95 99 rule, states that for normal distributions, 68% of observed data points will lie inside one standard deviation of the mean, 95% will fall within two standard deviations, and 99.7% will occur within three standard deviations. WebbThe probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes. Probability of event to happen P (E) = Number of …

The support of a probability mass function refers to the set of values that the discrete random variable can take. In this example, the support would be {1, 2, 3, 4, 5, 6} since the value of the dice can take on any of these values.
