Why has the continental 7's been imported into the UK? They, the continentals, 'bar' their 7's solely because their 'ones' have a downward 'tick' from the top of the number, which unless their 7's had a 'bar' on them they wouldn't be able to tell the difference. As we in the UK do not have this one 'tick' it is quite unecessary to 'bar' our 7's. Please stop putting a horizontal 'bar' on our UK 7's.

There is a group of balls, either red or blue. The number of red balls is not necessarily the same as blue balls.

We have 2 boxes, A and B. We are to assign the balls to the box. Each ball has a probability P that will be assigned to box A and 1-P to box B. This probability P varies for different balls.

After the assignment is done, we are to get a ball from the box A. What is probability that the ball I get is red (and similarly blue)?

1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111=123456789 87654321
