Difference of gaussian distributions

For a random variable x with gaussian or normal distribution, the probability distribution function is p x 1. Whats the difference between a multivariant gaussian and a. The difference is that the t distribution is leptokurtic, and so has higher kurtosis than the normal distribution. What is the difference between the tdistribution and.
