Let Y be a normally distributed random variable measuring the average daily energy dissipation of an engine. Given that Y has mean µ = 2 and P(Y ≤ 1) = 0.24, then determine the probability that at least 3 units of energy are dissipated in a chosen day. (Hint: use symmetry of the normal distribution about the mean)
