becuse 8 is in a day and the only thing could be 0 becuse in a hour you might not get much in an hour cuz an day is 24 hours but there might be a chance to be 1 but its mostly 0.
You can use the Law of Cosines (a^2=b^2+c^2-2bc cosA)
a^2=4^2+4^2-2*4*4*cos45°
a^2=32-32cos45°
a^2=32(1-cos45°)
a=√(32(1-cos45°))
a≈3.06 units (to nearest hundredth of a unit)
A probability experiment is conducted in which the sample space of the experiment is S={7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,
