It is not. 4 pm is two thirds of a 24-hour day since midnight and 2/3 = 0.6667 (approx).
There is a 6.667% chance (one in 15) of that happening. Math: p = (3/10)*(2/9) = .06667
To find the relative rate, you compare the rates of two different reactions under the same conditions. The relative rate is calculated by dividing the rate of one reaction by the rate of another reaction. This comparison helps in understanding how the rates of the reactions relate to each other.
