# If variance of x is 5, then find the variance of (2 – 3x)(a) 10(b) 45(c) 5(d) -13

## Question

## Solution 1

The variance of a random variable X is given by Var(X). If we have a new variable Y = aX + b, where a and b are constants, then the variance of Y is given by Var(Y) = a^2 * Var(X).

In this case, X has a variance of 5, and we want to find the variance of Y = 2 - 3X.
