:D correct in every detail. If the ball falls such that it either hits the hoop or goes through it, the chances are 5/9 it will hit the hoop and 4/9 it will go straight through so it's 25% more likely to hit the hoop...

Quarterly maths question and a little easier this time. If a curve such as a hyperbola disappears off to infinity what is the name given to the two straight lines that the curve gets progressively closer to without ever actually touching?

2+3=10 2+3=5 5x2=10
7+2=63 7+2=9 9x7=63
6+5=66 6+5=11 11x6=66
8+4=96 8+4=12 12x8=96

9+7=? 9+7=16 16x9=144

well done Buzzie

is it the binary scale

3=11
4=100
5=101
6=110
7=111
8=1000
9=1001

therefore 1001 = 9
