what do the three random variables with the same variance what does random variables have variance what would you think when there is a correlation with three random variables? why do random variables have the same variance when three random variables have the same variance what will the covariances look like? what happens when the variance of the a variable is the same if three random variables have the same variance, what will the co variances look like what will your variance be if three random variables have the same variance? does a random variable have the same variance what's a random variable that has the same variance? what is the relationship between variables with the same variance what is the difference between variance and covariance what do covariances look like in a random set of variables what does random variation mean if three random variables have the same variance, what will the covariances what is the probability that 3 random variables have the same variance what does if you have three random variables that have the same variance look like? what would the co variance look like what do the covariances of two random variables look like what do you get when you have three variables that have the same variance
