7) Suppose that X and Y are two independent measurements. We can treat these measurements as random variables, where X has the mean of 1 and standard deviation of 2, and Y has the mean of 2 and the standard deviation of 3. For the transformations below, find the mean, variance, and the standard deviation. a) X+Y b) X-Y c) 2X+Y d) X-2Y+1

Given the situation where the failure of a structure is given according to the following condition: DeadLoad + LiveLoad is greater than the Resistance If the variables are acting independently from each other, and each one is normally distributed as follows: DeadLoad ~ N(100,25), LiveLoad ~ N(150,50) and Resistance ~ N(300,20). Compute the failure probability of the structure.
