Bingo Card

A bingo Card contains 24 numbered spaces and one free space (blank), with which you play BINGO. The numbers are assigned at random on each card and are arranged in five columns of five numbers each by five rows (5 x 5 = 25 in total including the blank square).

The numbers in the B column are between 1 and 15, in the I column between 16 and 30, in the N column (containing four numbers and the free space) between 31 and 45, in the G column between 46 and 60, and in the O column between 61 and 75.

According to one calculation, there are approximately 552,446,474,061,128,648,601,600,000 (five hundred fifty-two septillion, four hundred forty-six sextillion, four hundred seventy-four quintillion, sixty-one quadrillion, one hundred twenty-eight trillion, six hundred forty-eight billion, six hundred one million, six hundred thousand) possible arrangements of the numbers on a bingo card.

If you could print a million cards per second, it would take 17,505,972,382,599.7 years to print every possible bingo card. And only 4,976,640,000 cards would have the same twenty four numbers, but in a different arrangement.
