The inclusion/exclusion principle states that
That is, the union has as many members as the sum of the number of members of the individual sets, minus the number of elements contained in both sets (to avoid double-counting).
Therefore,
will have the most elements when the sets
and
are disjoint, i.e.
, which would mean the most we can can in this case would be
(Note that
denotes the cardinality of the set
.)

Answer:
6 hours and 45 minutes
Step-by-step explanation:
First, convert 12 hours into minutes.
12*60=720
Convert 5 hours to minutes and add 15
5*60=300+15=315
Subtract 720 from 315.
720-315=405
Convert into hours and minutes.
405/60=6.75
0.75 of an hour is 45 minutes so the answer is 6 hours and 45 minutes.
