2/3
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
Relative error= Pretend we're talking about weight... You thought you were 150 pounds, but you're actually 160 150 pounds is wrong, while 160 is your actual weight Relative Error= 160-150 _______ 150 So it's Actual weight minus wrong weight divided by wrong weight So 160-150= 10 10/150= .0666666667 or if rounded to the nearest thousand, it's .06667 Hope that helped :)
