Chris and Jo decide to play a game. They put some red and some blue
ribbons in a box.
They each pick a ribbon from the box
without looking (and without replacing
them).
Jo wins if the two ribbons are the same
colour and Chris wins if the two ribbons
are a different colour.
How many ribbons of each colour would you need in the box to make it a
fair game?
Is there more than one way to make a fair game?

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle
