Let X be a continuous random variable. Express the distribution function and probability density of the random variable Y = −X in terms of those of X

2. Let X be an N(3, 4) distributed random variable. Use the rule for normal random variables under change of units and Table B.1 to determine the probabilities P(X ≥ 3) and P(X ≤ 1).
