Our calendar has a 400-year cycle.
B. H. Brown noticed that the number of times the thirteenth of the month falls on each of the days of the week in the 4800 months of a cycle is as follows:
Sunday 687
Monday 685
Tuesday 685
Wednesday 687
Thursday 684
Friday 688
Saturday 684
From this he deduced that the thirteenth was more likely to fall on
Friday than on any other day. Explain what he meant by this.
