Extracted text: 1. . Define (write) the probubility density of a normal distribution with mean -7 and standard deviation a-5: i. Write the munment generating lunction on i. Deline (write) the peobability density of a standand normul distribution. 4. i Ifa pair of random variables X and Y have a Bivariate Normal distribution. with u=9. =5. a - 8, , with correlation between X and Y is p. write their jeint probability density.
