1. and are two independent measurements. =10±1and =30±2, where 10 and 30 are the means of the measurements and , respectively. Also, 1 and 2 are the standard deviation (uncertainty) associated with the measurements and , respectively. Thus, these measurements can be treated as independent random variables. Find the mean, variance, and standard deviation of the following combinations. a)1=2+2
b)2=−3+1
